Adonis is playing a prank on his dad by replacing his shampoo with hot sauce. Every day, after his dad showers, Adonis replaces the shampoo with 1/2 an ounce of hot sauce. He knows his dad uses 1 oz of shampoo a day from a new 10 oz bottle that no one else uses.

Question: After 4 days, what percentage of the liquid in the bottle is hot sauce?
Answer: Each day, the shampoo bottle goes down 1/2 an ounce because 1 - (1/2) = 1/2
After four days the shampoo bottle is 2 ounces lower because 4 x (1/2) = <<4*(1/2)=2>>2
After four days, the shampoo bottle has 8 ounces of liquid left because 10 -2 = <<10-2=8>>8
After four days the shampoo bottle has 2 ounces of hot sauce 4 x (1/2) = <<4*(1/2)=2>>2
The proportion of hot sauce in the bottle is .25 because 2 / 8 = <<2/8=.25>>.25
The percentage of hot sauce is 25% because .25 x 100 = <<.25*100=25>>25

Two friends, Hubert and Ian, are planning to have a pizza party. One box of pizza is worth $14, and a can of soda is worth $1.80. Hubert orders eight boxes of pizza and ten cans of soda. Ian buys ten boxes of pizza and fifteen cans of soda.

Question: How much do they spend in all?
Answer: The number of boxes of pizza is 8 + 10 = <<8+10=18>>18 boxes.
The number of cans of soda is 10 + 15 = <<10+15=25>>25 cans.
The eighteen boxes of pizza cost 18 x $14= $<<18*14=252>>252.
The cost of 25 cans of soda is 25 x $1.80= $<<25*1.8=45>>45.
Therefore, the total amount they spend is $252 + $45 = $<<252+45=297>>297

The price per organic egg is 50 cents. The price of a tray of eggs that contains 30 eggs is $12.

Question: How much can you save, in cents, per egg if you buy a tray versus individual eggs?
Answer: The price per egg in a tray is $12/30 eggs = $<<12/30=0.4>>0.4/egg.
The equivalent of $0.4 in cents is $0.4 x 100 cents/dollar = <<0.4*100=40>>40 cents.
Hence, you can save 50 cents - 40 cents = <<50-40=10>>10 cents per egg if you buy a tray.

There are 10 books on the table. Two-fifths of them are reading books and three-tenths of them are math books. There is one fewer science book than math books and the rest are history books.

Question: How many history books are there?
Answer: Out of the 10 books, 10 x 2/5 = <<10*2/5=4>>4 are reading books.
While 10 x 3/10 = <<10*3/10=3>>3 are math books.
There are 3 - 1 = <<3-1=2>>2 science books.
So, the total number of reading, math, and science books is 4 + 3 + 2 = <<4+3+2=9>>9.
Thus, there is only 10 - 9 = <<10-9=1>>1 history book.

To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each.

Question: How many pops must be sold to buy 100 pencils?
Answer: To buy 100 pencils the school needs 100 * $1.80 = $<<100*1.80=180.00>>180.00.
Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $<<1.50-.90=.60>>.60.
So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice-pop = <<180/.60=300>>300 ice-pops.

Marjorie works as a baker. Every day, she makes twice as many cakes as she did the day before. On the sixth day, she makes 320 cakes.

Question: How many cakes did Marjorie make on the first day?
Answer: As the number of cakes doubles each day, Marjorie must have made 320 cakes / 2 = <<320/2=160>>160 cakes on the fifth day.
So on the fourth day, she must have made 160 cakes / 2 = <<160/2=80>>80 cakes.
This means that on the third day, she made 80 cakes / 2 = <<80/2=40>>40 cakes.
On the second day, she made 40 cakes / 2 = <<40/2=20>>20 cakes.
So on the first day, she made 20 cakes / 2 = <<20/2=10>>10 cakes.

Albert noticed a flock of geese flying together in a V formation in the sky overhead. One half of the geese broke off from the formation, flew toward the earth, and landed in some trees. Then, 4 geese flew up, out of the trees, and joined those already flying in the air to make a new V formation in the sky.

Question: If the final number of geese flying in the V formation was 12, how many geese were in the first formation Albert noticed in the sky?
Answer: If the final number of geese was 12, which included the 4 that joined from the trees, then before these 4 joined, there were 12-4=<<12-4=8>>8 geese in the sky.
Since these 8 geese represent the half of geese remaining, then the initial formation contained 8*2=<<8*2=16>>16 geese.

Jenna is planning a road trip. She plans on driving the first 200 miles, and her friend will drive the last 100 miles. They plan on taking 2 30-minute breaks.

Question: If Jenna drives 50 miles per hour and her friend drives 20 miles per hour, how many hours will they spend on the road trip?
Answer: Jenna will drive 200 miles at a rate of 50 miles per hour, so she will drive for 4 hours.
Her friend will drive 100 miles at a rate of 20 miles per hour, so Jenna's friend will drive for 5 hours.
They will spend a total of 60 minutes on breaks because 30 minutes + 30 minutes = <<30+30=60>>60 minutes.
Thus, they will spend 1 hour on breaks because there are 60 minutes in an hour.
The road trip will take a total of 1+4+5 = <<1+4+5=10>>10 hours.

Carlson bought land that cost $8000 and additional land that cost $4000. He initially owned 300 square meters of land.

Question: If the land he bought costs $20 per square meter, how big is his land after buying the new land?
Answer: Carlson bought land that cost $20 per square meter, therefore the size of the land he bought is 8000/20 = 400.
And the size of the other land he bought is 4000/20 = <<4000/20=200>>200.
Therefore the total size of the land he owns is 400+200+300 = <<400+200+300=900>>900.

Janice gets paid $10 an hour for the first 40 hours she works each week, and $15 each hour of overtime after that.

Question: If Janice works 60 hours one week, how much money does she make?
Answer: Janice makes during her first 40 hours of work $10/hour * 40 hours = $<<10*40=400>>400.
Janice works 60 hours - 40 hours = <<60-40=20>>20 hours during her overtime.
Janice makes from working overtime $15 * 20 = $<<15*20=300>>300.
The total she makes a week is $400 + $300 = $<<400+300=700>>700.
#### 700
Laura took six trips to park. On each trip, she spent 2 hours at the park and an additinal 30 minutes walking to and from the park.

Question: What percentage of the total time she took for her trips to the park did Laura spend in the park?
Answer: During 6 days, Laura would spend 2 * 6 = <<2*6=12>>12 hours in the park.
If it takes 30 minutes (or 0.5 of an hour) walking to and from the park, then for the six trips, it would take her an additional 0.5 * 6 = <<0.5*6=3>>3 hours to walk to and from the park.
In total, she would spend a total of 12 + 3 = <<12+3=15>>15 hours on her six trips.
So, the fraction of time spent in the park would be 12 / 15 = <<12/15=0.8>>0.8.
Thus, converting fraction to percentage, Laura spent 0.8 * 100% = 80% of her trip time at the park.

Seymour runs a plant shop. He has 4 flats of petunias with 8 petunias per flat, 3 flats of roses with 6 roses per flat, and two Venus flytraps. Each petunia needs 8 ounces of fertilizer, each rose needs 3 ounces of fertilizer, and each Venus flytrap needs 2 ounces of fertilizer.

Question: How many ounces of fertilizer does Seymour need in total?
Answer: First find the total number of petunias: 4 flats * 8 petunias/flat = <<4*8=32>>32 petunias.
Then find the total number of roses: 3 flats * 6 roses/flat = <<3*6=18>>18 roses.
Now find how much fertilizer Seymour needs for the petunias: 32 petunias * 8 oz/petunia = <<32*8=256>>256 oz.
Now find how much fertilizer Seymour needs for the roses: 18 roses * 3 oz/rose = <<18*3=54>>54 oz
Now find how much fertilizer Seymour needs for the Venus flytraps: 2 Venus flytraps * 2 oz/Venus flytrap = <<2*2=4>>4 oz.
Now add up the fertilizer for all three plants: 256 oz + 54 oz + 4 oz = <<256+54+4=314>>314 oz.

Tom's brother is 4 times as old as Tom's dog.

Question: If in 6 years, Tom's brother will be 30 years, how old is Tom's dog going to be in six years?
Answer: If in six years Tom's brother will be 30 years old, he is currently 30-6 = <<30-6=24>>24 years old.
Since Tom's brother is 4 times as old as Tom's dog, Tom's dog is 24/4 = <<24/4=6>>6 years old currently.
Tom's dog will be 6+6 = <<6+6=12>>12 years old in six years.

Mike began to train to play basketball every day for a tournament. One day he plays a maximum of 2 hours. After a week of training, he increased the maximum time to 3 hours.

Question: How many hours did Mike train during the first two weeks?
Answer: One week is 7 days, so for one week, Mike trained for 7 * 2 = <<7*2=14>>14 hours.
The second week he began to train for 3 hours a day, so he trained for 7 * 3 = <<7*3=21>>21 hours.
That means Mike in total trained for 21 + 14 = <<21+14=35>>35 hours.
