Before throwing the cookies, Alice and Bob baked 74 + 7 = 81 cookies. After throwing the cookies, they baked 5 + 36 = 41 cookies. In total, they baked 81 + 41 = 122 cookies. They threw 122 - 93 = 29 cookies on the floor.
The answer: 29
Reverse engineering the question: Alice and Bob decided to bake cookies for their first date. Alice baked 74 chocolate chip cookies and Bob baked 7 peanut butter cookies. After accidentally throwing some on the floor, Alice baked 5 more cookies and Bob baked 36 more. If they had 93 edible cookies at the end, how many were accidentally thrown on the floor?


Reasoning and answer: Her goal is 1 hour a day for 5 days so on a weekly basis, she exercises 1 * 5 = 5 hours. If she works 5 hours a week for 8 weeks then she exercises 5 * 8 = 40 hours in 8 weeks.
The answer: 40
What was the question?
Question: Jane's goal is to exercise 1 hour a day, 5 days a week. If she hits her goal weekly for 8 weeks, how many hours has Jane exercised?


Teagan saved 1 cent (.01) x 200 = $2. Rex has 5 cents (.05) x 100 = $5. Toni has 10 cents (.10) x 330 = $33. Together, the three kids saved $2 + $5 + $33 = $40.
The answer: 40
Reverse engineering the question: Teagan saved 200 pennies in her piggy bank. Rex has a mason jar filled with 100 nickels. Toni has 330 dimes stashed inside a giant mug. How much money did the three kids save altogether?


Reasoning and answer: Since Guise was eating 2 more hot dogs each day than the previous day and ate 10 hot dogs on Monday, he ate 10 + 2 = 12 hot dogs on Tuesday. By Tuesday Guise had eaten 12 + 10 = 22 hot dogs. On Wednesday, after eating two more hot dogs than the previous day, the total number of hot dogs he ate is 12 + 2 = 14. In the three days, Guise ate 14 + 22 = 36 hotdogs.
The answer: 36
What was the question?
Question: Guise went to a restaurant and ate ten hot dogs on a Monday. That week, he ate two more dogs each day than the previous day. How many hot dogs had Guise eaten by Wednesday that week?


He gets his pool cleaned 30 / 3 = 10 times a month. Each time he gets it cleaned he tips 150 * .1 = $15. So he pays 150 + 15 = $165. So he pays 165 * 10 = $1650 a month on cleaning. The chemicals cost 200 * 2 = $400. So in total, he pays 1650 + 400 = $2050.
The answer: 2050
Reverse engineering the question: John gets his pool cleaned every 3 days. It cost $150 each time and he gives the guy a 10% tip each time he comes to clean. Then twice a month he needs to use $200 of chemicals. How much does his pool cost a month?


Max gets 1 + 2 = 3 trains per year. He repeats this for 5 years, meaning he gets 5 * 3 = 15 trains. When this number is doubled by his parents, it becomes 15 * 2 = 30 trains. Since he already had 15 model trains, his total becomes 15 + 30 = 45 trains.
The answer: 45
Reverse engineering the question:
Max likes to collect model trains. He asks for one for every birthday of his, and asks for two each Christmas. Max always gets the gifts he asks for, and asks for these same gifts every year for 5 years. At the end of the 5 years, his parents give him double the number of trains he already has. How many trains does Max have now?
