There are enough provisions in a castle to feed 300 people for 90 days. After 30 days, 100 people leave the castle.

Question: How many more days are left until all the food runs out?
Answer: After 30 days, there will be enough food left to sustain 300 people for 90 days – 30 days = 60 days.
After the 100 people leave, there will be 300-100 = <<300-100=200>>200 people left.
The 200 people will eat 200/300 = 2/3 as much food as the original group of people in the castle.
The 60 days' worth of food will last this smaller group for 60 days / (2/3) = <<60/(2/3)=90>>90 more days.

Madeline spends 18 hours a week in class. She spends 4 hours per day working on homework. She spends 8 hours per day sleeping. She works part-time 20 hours per week.

Question: How many hours left over does Madeline have?
Answer: Madeline spends 4*7=<<4*7=28>>28 hours on homework.
She spends 8*7-56 hours sleeping.
Therefore, she is busy 28+18+56+20=<<28+18+56+20=122>>122 hours per week.
There are 7*24=<<7*24=168>>168 hours per week.
Thus, Madeline has 168-122=<<168-122=46>>46 hours left over.

Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books.

Question: If Rebecca received 40 books, how many books did Roselyn have before?
Answer: If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3*40 = 120 books.
Rebecca and Mara's total number of books is 120+40 = <<120+40=160>>160 books.
If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60+160 = <<60+160=220>>220 books.
#### 220
Natalie's sister had 8 small diaries in her locker. Last summer she bought double the number of diaries she had and then lost 1/4 of what she had.

Question: How many diaries does Natalie's sister have now?
Answer: Natalie's sister bought 2 * 8 = <<2*8=16>>16 diaries.
So she then had 16 + 8 = <<16+8=24>>24 diaries.
Afterwards, she loses 1/4 * 24 = <<24*1/4=6>>6 diaries.
So, Natalie's sister now has 24 - 6 = <<24-6=18>>18 diaries.

Austin bought his seven friends each a robot. Each robot costs $8.75. He was charged $7.22 total for tax. He left with $11.53 in change.

Question: How much did Austin start with?
Answer: First we need to find the total amount for the robots. 7 robots * $8.75 per robot = $<<7*8.75=61.25>>61.25 in total.
Now we need to add in the tax $61.25 for the robots + $7.22 for tax = $<<61.25+7.22=68.47>>68.47 total spent in store.
Now to find what was the beginning amount we take the $68.47 total spent in-store + $11.53 in change = $<<68.47+11.53=80>>80 to start.

A shady restaurant is charging customers gratuities after taxes without them being aware.

Question: If my total bill was $140, the sales tax in my city is 10%, I ordered a NY Striploin for $80, and I ordered a glass of wine for $10, how much did they charge me for gratuities?
Answer: The total bill before taxes or gratuities was $80 for the steak + $10 for the wine = $80+$10 = $<<80+10=90>>90
If the tax is 10%, then the taxes paid were $90 * 10% = $<<90*10*.01=9>>9
That means that the total bill before gratuities was $90 + $9 = $<<90+9=99>>99
If the final bill was $140, then you were charged $140-$99 = $<<140-99=41>>41 for gratuities

Jay & Gloria were hosting a 4th of July party at their house. Jay invited 22 people and Gloria invited 36. They wanted to buy small American flags for everyone. The craft store was having a sale on small flags, 5 flags for $1.00.

Question: If they wanted all of their guests to have a flag and they also wanted 1 flag each, how much would they spend at the craft store?
Answer: Jay invited 22 guests and Gloria invited 36 so they invited 22+36 = <<22+36=58>>58 guests
They also each wanted a flag so in total they would need 1+1+58 = <<1+1+58=60>>60 flags
The craft store has them on sale at 5 for $1.00 and they need 60 flags so the flags will cost them 60/5 = $12.00

It takes 15 mink skins to make a coat. Andy buys 30 minks and each mink has 6 babies, but half the total minks are set free by activists.

Question: How many coats can he make?
Answer: First find the total number of baby minks: 30 minks * 6 babies/mink = <<30*6=180>>180 minks
Add this to the number of adult minks: 180 minks + 30 minks = <<180+30=210>>210 minks
Then divide this number in half to find how many aren't set free: 210 minks / 2 = <<210/2=105>>105 minks
Then divide the remaining number of minks by the number of minks per coat to find the number of coats: 105 minks / 15 minks/coat = <<105/15=7>>7 coats

A used car lot has 24 cars and motorcycles (in total) for sale. A third of the vehicles are motorcycles, and a quarter of the cars have a spare tire included.

Question: How many tires are on the used car lot’s vehicles in all?
Answer: The used car lot has 24 / 3 = <<24/3=8>>8 motorcycles with 2 tires each.
The lot has 24 - 8 = <<24-8=16>>16 cars for sale
There are 16 / 4 = 4 cars with a spare tire with 5 tires each.
The lot has 16 - 4 = <<16-4=12>>12 cars with 4 tires each.
Thus, the used car lot’s vehicles have 8 * 2 + 4 * 5 + 12 * 4 = 16 + 20 + 48 = <<8*2+4*5+12*4=84>>84 tires in all.
#### 84
Samuel bought 2 dozen doughnuts and Cathy bought 3 dozen doughnuts. They planned to share the doughnuts evenly with their 8 other friends.

Question: How many doughnuts will each of them receive?
Answer: Since 1 dozen is equal to 12, then Samuel has 2 x 12 = <<24=24>>24 doughnuts.
While Cathy has 3 x 12 = <<3*12=36>>36.
They both have 24 + 36 = <<24+36=60>>60 doughnuts together.
There are 8 friends + 1 (Samuel) + 1 (Cathy) = <<8+1+1=10>>10 that will share the doughnuts.
Thus, each of them will get 60/10 = <<60/10=6>>6 doughnuts.

A roadwork company is paving a newly constructed 16-mile road. They use a mixture of pitch and gravel to make the asphalt to pave the road. Each truckloads of asphalt uses two bags of gravel and five times as many bags of gravel as it does barrels of pitch to make. It takes three truckloads of asphalt to pave each mile of road. The company paved 4 miles of road on one day, then one mile less than double that on the second day.

Question: How many barrels of pitch will the company need to finish the remaining road on the third day?
Answer: On the second day, the company paved 4 * 2 - 1 = <<4*2-1=7>>7 miles.
The company has 16 - 7 - 4 = <<16-7-4=5>>5 miles of road remaining to pave.
They will need 3 * 5 = <<3*5=15>>15 truckloads of asphalt to pave 5 miles of road.
For 15 truckloads, they will need 15 * 2 = <<15*2=30>>30 bags of gravel.
Thus, the company will need 30 / 5 = <<30/5=6>>6 barrels of pitch to finish the road on the third day.

Question: How much money will she have left after she pays the taxes?
Answer: The amount in taxes Dorothy needs to pay is 18/100 * 60000 = $<<18/100*60000=10800>>10800.
So she is going to be left with 60000 - 10800 = $<<60000-10800=49200>>49200.
#### 49200
Kantana loves chocolate. Every Saturday she goes to the candy store and buys 2 chocolates for herself and 1 for her sister. This last Saturday she picked up an additional 10 chocolates as a birthday gift for her friend Charlie.

Question: How many chocolates did Kantana end up buying for the month?
Answer: There is 1 Saturday in a week and there are 4 weeks in a month so there are 1 * 4= <<1*4=4>>4 Saturdays in a month (on average)
If Kantana buys herself 2 chocolates every Saturday then this means she buys 2 * 4=<<2*4=8>>8 chocolates for herself for the month.
Kantana also buys her sister 1 chocolate on these trips so she is picking up an additional 1* 4=<<1*4=4>>4 additional chocolates for her sister for the month.
Kantana decided to also purchase some chocolates for her friend Charlie for his birthday. She bought Charlie 10 chocolates. This means that for the month she bought 10 chocolates for Charlie, 4 chocolates for her sister, and 8 chocolates for herself, 10+4+8= <<10+4+8=22>>22 chocolates bought in total for the month.

Martha needs 4 cups of berries and 2 cups of heavy cream to make 1 quart of ice cream. She wants to make 1 quart of strawberry ice cream and 1 quart of raspberry ice cream. At the farmers market, the 2 cup packages of strawberries are $3.00 each and the 2 cup package of raspberries are $5.00 each. The heavy cream is sold for $4.00 for a 4 cup container.

Question: How much will it cost her to make 1 quart of each ice cream?
Answer: She needs 4 cups of strawberries per quart of ice cream and the strawberries are sold in 2 cup packages. So 4/2 = <<4/2=2>>2 packages of strawberries
The strawberries cost $3.00 per package and she needs 2 so 3*2=$<<3*2=6.00>>6.00
She needs 4 cups of raspberries per quart of ice cream and the raspberries are sold in 2 cup packages. So 4/2 = <<4/2=2>>2 packages of raspberries
The raspberries cost $5.00 per package and she needs 2 so 5*2 = $<<5*2=10.00>>10.00
Every quart needs 2 cups of heavy cream and she's making 2 quarts so 2*2 = <<2*2=4>>4 quarts
She will spend $6.00 on strawberries, $10.00 on raspberries and $4.00 on heavy cream bringing the total to 6+10+4 = $<<6+10+4=20.00>>20.00

Question: How much will Eve spend on the gifts?
Answer: A small knife is twice the amount of the utensils that costs $10.00 so the knife costs 2*10 = $<<2*10=20.00>>20.00
All total, each little kit will costs $14.00 for mitts, $16.00 for an apron, $10.00 for utensils and $20.00 for a knife for a total of 14+16+10+20 = $<<14+16+10+20=60.00>>60.00
Each kit costs $60.00 and they are currently 25% off so that's a savings of 60*.25 = $<<60*.25=15.00>>15.00
The kits are $60.00 and they are $15.00 off so they now cost 60-15 = $<<60-15=45.00>>45.00
She needs to buy 3 kits and each kit costs $45.00 so that's 3*45 = $<<3*45=135.00>>135.00

At a gathering, it was reported that 26 people took wine, 22 people took soda, and 17 people took both drinks.

Question: If each person could have taken one or more drinks regardless of what was reported, how many people altogether were at the gathering?
Answer: The number of people who took only wine is the difference between the number of people who took wine and those who took wine and soda which is 26 -17 = <<26-17=9>>9 people
In the same manner, the number of people who took only soda is 22-17 = <<22-17=5>>5 people
Therefore the total number present is the sum of those who took wine only, those who took soda only and those who took both which is 9+5+17 = <<9+5+17=31>>31 people

Bobby needed to make some trips with his truck and had only 12 gallons of gasoline. He drives to a supermarket 5 miles away and then drives back home. Then he headed to his farm which was 6 miles away. Two miles into the journey, he turned around and drove back home to retrieve some farming tools he forgot to take earlier and drove down to the farm.

Question: If he now has exactly 2 gallons of gasoline left, at what rate in miles per gallon has his truck been consuming gasoline?
Answer: The trip to the supermarket and back home covers 5+5=<<5+5=10>>10 miles.
The round trip of two miles each before he actually went to the farm covers 2+2=<<2+2=4>>4 miles.
Six miles to the farm and the total mileage is 10+4+6=<<10+4+6=20>>20 miles.
The truck consumed 12-2=<<12-2=10>>10 gallons of gasoline for the total journey.
So, the rate is 20/10= <<20/10=2>>2 miles per gallon.

Question: How many pieces of rope will he need to buy?
Answer: He needs 10*6=<<10*6=60>>60 feet
He loses 20*.25=<<20*.25=5>>5 feet each time
So he gets 20-5=<<20-5=15>>15 feet from each piece
That means he needs 60/15=<<60/15=4>>4 pieces of rope

Samuel swept the porch and cleared nine-tenths of the dust particles from it. As he walked across the porch afterward, his shoes left 223 dust particles behind.

Question: How many dust particles were on the porch before Samuel swept if there were 331 after he walked across it?
Answer: Before Samuel walked across the porch, there were 331 - 223 = <<331-223=108>>108 dust particles.
Those 108 were 1/10 of the original amount, so there were 108 * 10 = <<108*10=1080>>1080 dust particles on the porch before Samuel swept.

Kim's TV uses 125 watts of electricity per hour. She runs it for 4 hours a day.

Question: If electricity cost 14 cents per kw/h how many cents does her TV cost to run for a week?
Answer: She uses 4 hours/day * 125 watts/hour=<<4*125=500>>500 watt hours/day
That means she uses 500 watt hours/day * 7 days/week = <<500*7=3500>>3500 watt hours/week
This is 3500 watt hours / 1000 watts/kw = <<3500/1000=3.5>>3.5 kw hours
So her TV cost 3.5 kw hours/week * $0.14/kw hour = $<<3.5*0.14=0.49>>0.49/week

Adam earns $40 daily in his job. 10% of his money is deducted as taxes.

Question: How much money will Adam have earned after taxes after 30 days of work?
Answer: The amount of money deducted from Adam's daily pay is $40 / 10 = $<<40/10=4>>4.
So after deducting 10%, Adam’s daily pay is $40 – $4 = $<<40-4=36>>36.
This means that in 30 days he earns $36 * 30 = $<<36*30=1080>>1080.

Lucille is painting her room. Two of her walls are 3 meters wide and 2 meters tall. The third wall is 5 meters wide and 2 meters tall. The final wall is 4 meters wide and 2 meters tall.

Question: If each can of paint covers 2 square meters, how many cans of paint does Lucille need?
Answer: For the first set of walls, each wall covers 3 meters wide * 2 meters tall = <<3*2=6>>6 square meters.
There are two of these walls, so this becomes a total of 6 meters * 2 walls = <<6*2=12>>12 square meters.
The third wall covers 5 meters wide * 2 meters tall = <<5*2=10>>10 square meters.
The final wall covers 4 meters wide * 2 meters tall = <<4*2=8>>8 square meters.
So in total, the paint needs to cover 12 + 10 + 8 = <<12+10+8=30>>30 metres.
Since each can covers 2 meters, Lucille needs 30 meters / 2 = <<30/2=15>>15 cans of paint.

Answer: Carl starts with 12 marbles to play with but loses 1/2, 12 / 2 = <<12/2=6>>6 marbles Carl didn't lose.
Carl takes out 10 more marbles, 6 + 10 = <<6+10=16>>16 marbles.
Then Carl's mother brings him 25 new marbles to add to the 16 he has out of his jar, 25 + 16 = <<25+16=41>>41 marbles that Carl is going to put in his jar after he plays his marbles game.

Rene can finish reading 30 pages in 60 minutes. Lulu can read 27 pages in 60 minutes and Cherry can read 25 pages in 60 minutes.

Question: If they have been reading for 240 minutes now, how many pages have they finished reading in total?
Answer: Rene finished 30 x 4 = <<30*4=120>>120 pages in 240 minutes.
Lulu finished 27 x 4 = <<27*4=108>>108 pages in 240 minutes.
Cherry finished 25 x 4 = <<25*4=100>>100 pages in 240 minutes.
Therefore they have finished a total of 120 + 108 + 100 = 328 pages in 240 minutes.

Sonja makes her own peanut butter with peanuts and oil in a blender. She uses a ratio of two ounces of oil to smooth out every eight ounces of peanuts. Her last batch of peanut butter weighed 20 ounces.

Question: How many ounces of oil did she use?
Answer: Sonja uses 2 ounces of oil for 8 ounces of peanuts to make 2 + 8 = 10 ounces of peanut butter.
Her last batch weighed 20 ounces, so she made 20 / 10 = <<20/10=2>>2 times her ratio.
Thus, she used 2 * 2 = <<2*2=4>>4 ounces of oil.
