Reasoning and answer: The second rocket goes 500 * 2 = 1000 feet. So the total height is 500 + 1000 = 1500 feet.
The answer: 1500

Question: John builds a model rocket that can travel 500 ft in the air. He builds a second rocket that can travel twice as high. What is the combined height of the two rockets?
Caleb was left with 40 - 3 - 3 - 5 - 2 = 27 dandelion puffs to give to his friends. They each received 27 / 3 = 9 dandelion puffs.
The answer: 9
Reverse engineering the question: Caleb picked a handful of dandelion puffs. He gave 3 to his mom, another 3 to his sister, 5 to his grandmother, and 2 to his dog. Then, he divided the remaining dandelion puffs equally among his 3 friends. How many dandelion puffs did each friend receive if he originally picked 40 dandelion puffs?
Reasoning and answer: First find the number of inches in each flight of stairs: 12 steps * 8 inches / step = 96 inches. Then find the net number of flights of stairs Jack went down: 6 flights - 3 flights = 3 flights. Then multiply than number by the number of inches per flight to find how many inches further down he is: 96 inches / flight * 3 flights = 288 inches. Then divide that number by 12 to find the number of feet down he is: 288 inches / 12 inches / foot = 24 feet.
The answer: 24

Question: Jack goes up three flights of stairs, then down six flights of stairs. If each flight of stairs has 12 steps that each each 8 inches high, how many feet further down is Jack than when he started?
15 keyboards at $20 per keyboard cost a total of 15 * $20 = $300. The total cost of printers and keyboards is $2050 so 25 printers cost $2050 - $300 = $1750. 1 printer cost $1750 / 25 = $70.
The answer: 70
Reverse engineering the question: A merchant bought 15 keyboards and 25 printers for a total of $2050. If a keyboard costs $20, how much does a printer cost?
Reasoning and answer: When Carla was waiting on Monday she counted 38 ceiling tiles and on Tuesday she counted them twice, 38 ceiling tiles x 2 = 76 times she counted a ceiling tile. She also counted 75 books in the room on Monday and counted them three times in a row on Tuesday, 75 books x 3 = 225 times she counted a book. On Tuesday Carla counted the ceiling tiles 76 times + counted books 225 times = 301 times Carla counted something on Tuesday.
The answer: 301
What was the question?
Question: To pass the time while she is waiting somewhere Carla likes to count things around her. While she is waiting for school to start on Monday she counts the tiles on the ceiling--38. While she is waiting for everyone to finish their tests after she has handed in hers, she counts the books in the room--75. On Tuesday Carla counts all the tiles twice in a row and she counts the books three times in a row when she has to wait for a long time for the teacher to finish handing out the graded tests. If every time Carla counts something counts as once, how many times has Carla counted something on Tuesday?
Reasoning and answer: After 10 years, growing at the rate of 3 inches every year, Haley will have grown by 3 * 10 = 30 inches. If she is currently 20 inches tall, her height after 10 years will be 20 + 30 = 50 inches.
The answer: 50
