He needs food for 21 days because 3 x 7 = 21. The puppy will eat 7 cups of food because 21 x (1 / 3) = 7. He needs 2 bags of food because 7 / 3.5 = 2. The food will cost him $4 because 2 x 2 = 4. It will cost $14 in total because 10 + 4 = 14.
The answer: 14
Reverse engineering the question: Mark just got a new puppy that cost $10. He also bought enough food for 3 weeks. He knows the puppy eats 1/3 cup of food a day. A bag of food with 3.5 cups costs $2. How much did all of this cost him?
Reasoning and answer: Mr. Smith bought 86 markers - 32 markers = 54 markers. Mr. Smith bought 54 markers 9 markers / box = 6 new boxes.
The answer: 6

Question: Mr. Smith had 32 markers in his classroom. He buys new boxes of markers that have 9 markers in each box. Now, he has 86 markers. How many new boxes did Mr. Smith buy?
The flight from NY to Hawaii will take 60 x 11 + 20 = 680 minutes. All the activities will take 120 + 240 + 30 + 40 + 70 = 500 minutes. For his nap, he has 680 - 500 = 180 minutes. To convert minutes to hours, he has 180 / 60 = 3 hours.
The answer: 3
Reverse engineering the question: Aren's flight from New York to Hawaii will take 11 hours 20 minutes. He spends 2 hours reading, 4 hours watching two movies, 30 minutes eating his dinner, 40 minutes listening to the radio, and 1 hour 10 minutes playing games. How many hours does he have left to take a nap?
Reasoning and answer: The lightsaber cost 1000 * 2 = $2000. So he has spent 2000 + 1000 = $3000.
The answer: 3000

Question: John buys a lightsaber toy. It is twice as expensive as all his other Star Wars toys combined. If his other Star Wars toys cost $1000, how much money has he spent in all after buying the lightsaber?
The garden is 220 * 120 = 26,400 square feet. The tilled land will take up half the area, and the trellises and raised beds will be the other half. Each half is 26,400 / 2 = 13,200 square feet. The trellises will take up 1 / 3 of the remaining land, so the raised beds will take 1 - 1 / 3 = 2 / 3 of the remaining land. So the total area of the raised bed area will be 13,200 square feet * (2 / 3) = 8,800 square feet.
The answer: 8800
Reverse engineering the question: Bob is building a vegetable garden. It is 220 feet long by 120 feet wide. Half of the garden is going to be tilled land. A third of the rest of it will have trellises for vining plants, and the rest will be devoted to raised beds. How big will the raised bed section of the garden be?
In the rooms with tall mirrors, Sarah saw her reflection a total of 10 reflections * 3 passes = 30 times. In the rooms with wide mirrors, Sarah saw her reflection a total of 5 reflections * 5 passes = 25 reflections. So Sarah saw her reflection a total of 30 + 25 = 55 times. In the rooms with tall mirrors, Ellie saw her reflection a total of 6 reflections * 3 passes = 18 times. In the rooms with wide mirrors, Ellie saw her reflection a total of 3 reflections * 5 passes = 15 times. So Ellie saw her reflection a total of 18 + 15 = 33 times. Therefore, Sarah and Ellie saw their reflections a total of 55 + 33 = 88 times.
The answer: 88
Reverse engineering the question:
Ellie went to visit a circus with Sarah and they both got lost in the house of mirrors. They have to travel through the house of mirrors a few times before they finally get out and when they leave, they discuss how many times they've seen their own reflections. Sarah says that every time they were in the room with tall mirrors, she saw her reflection 10 times and every time they were in the room with wide mirrors, she saw her reflection 5 times. Ellie says that every time they were in the room with tall mirrors, she saw her reflection 6 times and every time they were in the room with wide mirrors she saw her reflection 3 times. They both passed through the room with tall mirrors 3 times each and they both passed through the room with wide mirrors 5 times each. In total, how many times did Sarah and Ellie see their reflections?
