Roger had a 6-hour drive planned out. He didn't want to listen to music so he downloaded several podcasts. The first podcast was 45 minutes long. The second podcast was twice as long as that. The third podcast was 1 hour and 45 minutes long. His fourth podcast is 1 hour long.

Question: How many hours will his next podcast have to be to fill up the full 6 hours?
Answer: The second podcast was twice as long as the first so 2*45 = <<2*45=90>>90
1 hour is 60 mins. So his 1 hour and 45 min podcast is 60+45 = <<1*60+45=105>>105 minutes long
So far he has downloaded 45+90+105+60 = <<45+90+105+60=300>>300 min
If he converts 300 min to hours then he has 300/60 = <<300/60=5>>5 hours of podcasts downloaded
He has 5 hours of podcasts and his drive is 6 hours so he will need 6 - 5 = <<6-5=1>>1 more hour of podcasts

A group of six friends planned to buy a car. The cost of the car is $1700 and they plan to share the cost equally. They had a car wash to help raise funds, which would be taken out of the total cost. The remaining cost would be split between the six friends. At the car wash, they earn $500. However, Brad decided not to join in the purchase of the car.

Question: How much more does each friend have to pay now that Brad isn't participating?
Answer: Start by finding the total that is left, $1700 car price - $500 earned at car wash = $<<1700-500=1200>>1200 remaining.
So the six friends should pay $1200 / 6 people = $<<1200/6=200>>200 each.
Since Brad is not joining, then the 5 friends have to split Brad's share which is $200/5 = $<<200/5=40>>40 each.

John's camera broke so he decided to rent one for 4 weeks. It was a $5000 camera and the rental fee was 10% of the value per week. His friend who was there when it broke agreed to pay 40% of the rental fee.

Question: How much did John pay?
Answer: The rental fee is 5000*.1=$<<5000*.1=500>>500 per week
So it cost 500*4=$<<500*4=2000>>2000
His friend pays 2000*.4=$<<2000*.4=800>>800
So he pays 2000-800=$<<2000-800=1200>>1200

At peak hours, 11 am - 1 pm and 5 pm - 6 pm, the local fast-food restaurant serves 12 cars every 15 minutes. Off-peak times, they serve 8 cars every 15 minutes.

Question: From 4 pm - 6 pm, how many customers do they serve?
Answer: 5 pm-6 pm is one hour and they measure service in 15-minute blocks so 60/15 = <<60/15=4>>4 15 min blocks
At peak times, they serve 12 cars every 15 minutes so they serve 12*4 = <<12*4=48>>48 cars in 60 minutes
Off peak times, 4pm-5 pm, they serve 8 cars every 15 minutes so they serve 8*4 = <<8*4=32>>32 cars in 60 minutes
From 4pm-5 pm they serve 32 cars and from 5pm-6 pm they serve 48 cars so they serve 32+48 = 80 cars

Andrew installed hardwood flooring in his house. His bedroom took eight wooden planks, his living room took twenty planks, and his kitchen took eleven planks. The guest bedroom took two fewer planks than Andrew’s bedroom, and each of his two hallways took four planks. He accidentally ruined three planks in each bedroom by dragging furniture over them and had to replace them. He ended up with six leftover planks at the end.

Question: How many wooden planks did Andrew buy to start with?
Answer: Andrew’s guest bedroom took 8 - 2 = <<8-2=6>>6 wooden planks.
His hallways took 2 * 4 = <<2*4=8>>8 planks.
In two bedrooms, he ruined 3 planks each, so the bedrooms took an extra 3 * 2 = <<3*2=6>>6 planks.
In all, he used 8 + 20 + 11 + 6 + 8 + 6 = <<8+20+11+6+8+6=59>>59 planks for his whole house.
Andrew had 6 leftover planks, so he bought 59 + 6 = <<6+59=65>>65 wooden planks to start with.

Jeff was driving to the capital city to attend a conference. At first, he was driving at 80 miles/hour for about 6 hours, then the speed limit changed and he had to slow down to 60 miles/hour, and so he drove at this speed for 4 hours. Then he made a stop at a gas station. Once the car was full of gas, he drove at 40 miles/hour the rest of the trip for 2 hours.

Question: How many miles did he travel?
Answer: In the first stretch he drove 80 miles/hour x 6 hours = <<80*6=480>>480 miles
In the second stretch he drove 60 miles/hour x 4 hours = <<60*4=240>>240 miles
After the gas station he drove 40 miles/hour x 2 hours = <<40*2=80>>80 miles
In total he drove 480 miles + 240 miles + 80 miles = <<480+240+80=800>>800 miles

There are 10 students in a class. The average age of 9 of them is 8 years.

Question: By how many years will this average increase if the tenth student is (quite strangely) 28 years old?
Answer: 9 students have an average age of 8 years so the sum of their ages is 9*8 = <<9*8=72>>72 years
A tenth student who is 28 years old will make the sum 72+28 = 100 years
The new average age will be 100/10 = <<100/10=10>>10 years
This is 10-8 = <<10-8=2>>2 years higher than the previous average.

Jerry takes 2 antacids that weigh 2 grams each and are 5% zinc by weight. Then he takes three more smaller antacids that weigh 1 gram each and have 15% zinc.

Question: How many milligrams of zinc does he eat?
Answer: First find the total weight of the big antacids: 2 grams/antacid * 2 antacids = <<2*2=4>>4 grams
Then convert that weight to milligrams: 4 grams * 1000 mg/gram = <<4*1000=4000>>4000 mg
Then multiply that number by 5% to find how much zinc is in the big antacids: 4000 mg * 5% = <<4000*5*.01=200>>200 mg
Then find the total weight of the smaller antacids in milligrams: 3 antacids * 1 gram/antacid * 1000 mg/gram = <<3*1*1000=3000>>3000 mg
Then multiply that number by the percent of zinc to find the amount of zinc in the small antacids: 3000 mg * 15% = 450 mg
Then add the zinc Jerry gets from each set of pills to find the total amount of zinc he eats: 450 mg + 200 mg = <<450+200=650>>650 mg
#### 650
Tom weighs 150 kg. He manages to hold 1.5 times his weight in each hand while wearing a weight vest weighing half his weight.

Question: How much total weight was he moving with?
Answer: He was carrying 150*1.5=<<150*1.5=225>>225 kg in each hand
So he had 225*2=<<225*2=450>>450 kg in his hands
The weight vest weighed 150*.5=<<150*.5=75>>75 kg
So he had a total of 450+75=<<450+75=525>>525 kg he was moving

Jenny signs up for dinner theater with 5 of her friends. Each person pays $50 for the ticket and $10 for their entrée, and half the people also buy unlimited drink tickets for $30/person. Then the dinner theater is canceled due to COVID, and each person gets a 90% refund.

Question: How much money did the group of six friends lose?
Answer: First find the cost of the ticket and the entrée for each person: $50/person + $10/person = $<<50+10=60>>60/person
Then multiply that cost by the number of people to find the total cost of entrees and tickets: $60/person * 6 people = $<<60*6=360>>360
Now find how many people ordered drink tickets: 6 people / 2 = <<6/2=3>>3 people
Now find the total cost of the drink tickets: 3 people * $30/person = $<<3*30=90>>90
Now find the total cost of the evening: $90 + $360 = $<<90+360=450>>450
Now multiply this quantity by 90% to find the amount of the refund: $450 * .9 = $<<450*.9=405>>405
Now subtract the refund amount from the total cost to find how much money the friends lost: $450 - $405 = $<<450-405=45>>45

There were 15 males and 10 more girls at the party. Each attendee received 2 cans of soft drinks.

Question: If Mary bought several boxes of soft drinks where a box contains 8 cans and is priced at $5 for each box, how much did Mary spend on soft drinks?
Answer: There were 10 + 15 = <<10+15=25>>25 girls in the party.
So, there were a total of 15 + 25 = <<15+25=40>>40 attendees.
40 x 2 = <<40*2=80>>80 cans of soft drinks are needed.
So, Mary bought 80/8 = <<80/8=10>>10 boxes of soft drinks.
Therefore, Mary spent 10 x $5 = $<<10*5=50>>50 on soft drinks.

Jonas is trying to expand his wardrobe. He has 20 pairs of socks, 5 pairs of shoes, 10 pairs of pants and 10 t-shirts.

Question: How many pairs of socks does he need to buy to double the number of individual items in his wardrobe?
Answer: First, we must recognize that all pairs of shoes and socks are actually two items each, whereas the pants and the t-shirts are individual items. Therefore there are 20*2= <<20*2=40>>40 individual socks in 20 pairs of socks.
Similarly, there are 5*2=<<5*2=10>>10 individual shoes in 5 pairs of shoes.
Therefore, Jonas has 40+10+10+10= <<40+10+10+10=70>>70 individual items in his collection.
To double this number, we perform 70*2=<<70*2=140>>140.
This means we need 140-70=<<140-70=70>>70 new items to double the size.
Since there are 2 individual socks in each pair, we take 70/2= <<70/2=35>>35 new pairs of socks.

In one of the building blocks at Oakland High there are 5 classes. Each class uses 2 whiteboards each and each whiteboard needs about 20ml of ink for a day's use.

Question: If ink costs 50 cents per ml, how much (in dollars) would it cost to use the boards for one day?
Answer: Each ml of ink costs 50 cents so 20 ml costs 20*50 = <<20*50=1000>>1000 cents
There are 2 whiteboards in each class so each class needs 2*1000 cents = <<2*1000=2000>>2000 cents
There are five classes in the block so they all need 5*1*2000 cents = <<5*1*2000=10000>>10000 cents
100 cents make a dollar so 10000 cents make 10000/100 = $<<10000/100=100>>100

John starts a TV show. He pays $1000 per episode for the first half of the season. The second half of the season had episodes that cost 120% more expensive.

Question: If there are 22 episodes how much did the entire season cost?
Answer: The season is broken up into 22/2=<<22/2=11>>11 episode based on cost
The first 11 episodes cost 11*1000=$<<11*1000=11000>>11,000
The next set of episodes cost 1000*1.2=$<<1000*1.2=1200>>1200 more per episode
So they cost 1000+1200=$<<1000+1200=2200>>2200 each
So in total they cost 2200*11=$<<2200*11=24200>>24200
So in total the season cost 24200+11000=$<<24200+11000=35200>>35,200

Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye.

Question: How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?
Answer: First find the amount of dye each blouse takes: 20 dots/blouse * 10 ml/dot = <<20*10=200>>200 ml/blouse
Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml/blouse * 100 blouses = <<200*100=20000>>20000 ml
Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml/bottle = <<20000/400=50>>50 bottles

Elyse had 100 pieces of gum. She gave half to her brother Rick. He gave half of his to his friend Shane. Shane chewed 11 pieces of gum.

Question: How many pieces does Shane have left?
Answer: Elyse gave half of her 100 pieces of gum, or 100 / 2 = <<100/2=50>>50 pieces of gum, to Rick.
Rick gave half of his 50 pieces of gum, or 50 / 2 = <<50/2=25>>25 pieces of gum, to Shane.
Shane had 25 pieces of gum and chewed 11, so he had 25 – 11 = <<25-11=14>>14 pieces of gum left.

Samuel is arranging his grandma’s teacups. They are stored in boxes and inside the boxes, they are stacked 5 rows high with 4 cups in each row. Of the 26 boxes in her attic, 6 of the boxes contain pans, half of the remaining boxes contain decorations, and the rest of the boxes contain her teacups. Samuel breaks 2 of the cups every time he picks up one of the boxes.

Question: By the time Samuel has taken all of the teacups out of the boxes, how many teacups are left?
Answer: Taking the boxes of pans out of the total attic boxes shows that 26 boxes – 6 boxes of pans = 20 boxes are either decorations or teacups.
Since half of these boxes are decorations, the other half must be made up of 20 boxes / 2 = <<20/2=10>>10 boxes of teacups.
Each box of cups initially has 5 rows x 4 cups = <<5*4=20>>20 teacups inside.
Samuel breaks cups each time he picks up a box, which means each box now contains 20 – 2 = <<20-2=18>>18 teacups.
Therefore, there are 10 boxes * 18 teacups = <<10*18=180>>180 teacups left.
