First find the total number of tomatoes harvested: 18 plants * 7 tomatoes / plant = 126 tomatoes. Then divide that number by 2 to find how many tomatoes are left undried: 126 tomatoes / 2 = 63 tomatoes. Then divide that number by 3 to find how many tomatoes are turned into sauce: 63 tomatoes / 3 = 21 tomatoes. Then subtract that number from the number of undried tomatoes to find the remaining number of tomatoes: 63 tomatoes - 21 tomatoes = 42 tomatoes.
The answer: 42
Reverse engineering the question: Andy harvests all the tomatoes from 18 plants that have 7 tomatoes each. If he dries half the tomatoes and turns a third of the remainder into marinara sauce, how many tomatoes are left?


Reasoning and answer: If there are 50 spotted brown toads per acre, and this represents one - quarter of the brown toads, then there are 50 * 4 = 200 brown toads per acre. If for every 25 brown toads there is one green toad, then there are 200 / 25 = 8 green toads per acre.
The answer: 8

First find the total number of pages that are crumpled: 42 pages / 7 = 6 pages. Then find the total number of pages that are blurred: 42 pages / 3 = 14 pages. Then find the number of pages that are both blurred and crumpled by finding how many numbers are less or equal to 42 and divisible by both 3 and 7: there are two, 21 and 42. Then subtract the number of crumpled and blurred pages from the total number of pages, and add the number of pages that were double - counted because they were both blurred and crumpled: 42 pages - 6 pages - 14 pages + 2 pages = 24 pages.
The answer: 24
Reverse engineering the question: James has an old printer that crumples every seventh page and blurs the ink on every third page. If he prints 42 pages, how many are neither crumpled or blurred?


Reasoning and answer: Weng earns 12 / 60 = $0.2 per minute. Working 50 minutes, she earned 0.2 x 50 = $10.

Reasoning and answer: If Mark bought 50 cans of milk, the number of times Jennifer added 6 cans for every 5 that Mark bought is 50 / 5 = 10 times. The total number of additional cans she bought is 10 * 6 = 60 cans. If she initially had 40 cans, she went home with 40 + 60 = 100 cans of milk.
The answer: 100
What was the question?
Question:
Jennifer purchased 40 cans of milk at the store before meeting her classmate Mark, who was also buying milk. Jennifer bought 6 additional cans for every 5 cans Mark bought. If Mark purchased 50 cans, how many cans of milk did Jennifer bring home from the store?
