Reasoning and answer: For each liter of chlorine, I can save $10 x .20 = $2. For each box of soap, I can save $16 x .25 = $4. With the 3 liters of chlorine, I can save $2 x 3 = $6. With the 5 boxes of soap, I can save $4 x 5 = $20. Therefore, I can save a total of $6 + $20 = $26.
The answer: 26

Question: A liter of chlorine costs $10 and is now sold at 20% off. A box of soap that costs $16 is now sold at 25% off. How much will you save if you buy 3 liters of chlorine and 5 boxes of soap?
First find how long the second lock stalls them: 5 minutes * 3 - 3 minutes = 12 minutes. Then multiply that amount by 5 to find the total time the third lock stall the raccoon: 12 minutes * 5 = 60 minutes.
The answer: 60
Reverse engineering the question: Karen is constantly trying to stop the raccoons from getting in her trash. The first lock she tries stalls them for 5 minutes. The next lock stalls them for 3 minutes less than three times as long as the first lock. When Karen tries both locks at once, it stalled the raccoons for five times as long as the second lock alone. How long is that?
Reasoning and answer: Peter has 19 7 = 12 years of experience. Robert has 12 4 = 8 years of experience. Mike has 8 2 = 6 years of experience. Tom has 2 * 8 = 16 years of experience. Roger has 12 + 8 + 6 + 16 = 42 years of experience. Roger has to work another 50 42 = 8 years before he retires.
The answer: 8

Question: Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience. Peter said that when he came to the company his daughter was 7 years old, and now she is 19 years old. Tom then said he has twice as many years of experience as Robert. Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires?
The pen is shorter than the pencil by 2 centimeters, so it's 12 - 2 = 10 centimeters long. That means the rubber is 10 - 3 = 7 centimeters long. So all accessories are 7 + 10 + 12 = 29 centimeters long altogether.
The answer: 29
Reverse engineering the question: A pen is longer than the rubber by 3 centimeters, and shorter than the pencil by 2 centimeters. Considering the pencil is 12 centimeters long, what is the total length of the rubber, the pen, and the pencil altogether?
Reasoning and answer: In an hour, Emily can type 60 words * 60 minutes = 3600 words. It will take her 10800 / 3600 = 3 hours to write 10800 words.

Question: Emily can type 60 words per minute. How many hours does it take her to write 10,800 words?
Reasoning and answer: She found 10 quarters that are $0.25 each so she found 10 * .25 = $2.50. She found 3 dimes that are $0.10 each so she found 3 * .10 = $0.30. She found 3 nickels that are $0.05 each so she found 3 * .05 = $0.15. She found 5 pennies that are $0.01 each so she found 5 * .01 = $0.05. All total she found 2.50 + .30 + .15 + .05 = $3.00 in change.
The answer: 3
