First find the size of the second bell: 50 pounds * 2 = 100 pounds. Then find the size of the third bell: 100 pounds * 4 = 400 pounds. Then add the amount of bronze used for each bell to find the total: 100 pounds + 400 pounds + 50 pounds = 550 pounds.
The answer: 550
Reverse engineering the question: Martin is casting three bells for the church's belfry. The first bell takes 50 pounds of bronze, the second bell is twice the size of the first bell, and the third bell is four times the size of the second bell. How much bronze does he need total?


Reasoning and answer: Joe spends 4.50 * 3 = 13.50 on oranges. Joe spends 7 * 0.5 = 3.50 on juice. Joe spends 3 * 5 = 15 on honey. Each plant costs 18 / 2 = 9 dollars. Joe spends 9 * 4 = 36 on plants. Joe spends a total of 13.50 + 3.50 + 15 + 36 = 68 dollars at the market.
The answer: 68
What was the question?
Question: Joe buys 3 oranges, 7 juices, 3 jars of honey, and 4 plants at the market. The fruit costs $4.50 each, the juice was 50 cents each, the jars of honey were $5, and the plants were 2 for $18. How much does Joe spend at the market?


Jerry will spend 8 games x 2 hours per game = 16 hours watching one daughter play her games. He will spend 16 x 2 = 32 hours watching both daughters play their games. He will spend 8 games x 4 hours of practice = 32 hours watching one daughter practice. He will spend 32 x 2 = 64 hours watching both daughters practice. He will spend a total of 32 hours watching games + 64 hours watching practice = 96 hours.
The answer: 96
Reverse engineering the question: Jerry’s two daughters play softball on different teams. They each have 8 games this season. Each team practices 4 hours for every game they play. If each game lasts for 2 hours, how many hours will Jerry spend at the field watching his daughters play and practice altogether?


Reasoning and answer: Bianca = 12.5 hours. Celeste 2 * 12.5 = 25 hours. McClain = 25 - 8.5 = 16.5 hours. Total + 12.5 + 25 + 16.5 = 54 hours. 54 hours * 60 minutes = 3240 minutes. Bianca, Celeste and McClain worked a total of 3240 minutes last weekend.
The answer: 3240
What was the question?
Question: Bianca worked for 12.5 hours last weekend. Celeste worked for twice that amount of time and McClain worked 8.5 hours less than Celeste. How many minutes did the 3 people work in total?


The train ride takes Andrew 2 * 10 = 20 hours. Together, the subway ride and the train ride take Andrew 10 + 20 = 30 hours. With an additional bike ride of 8 hours to reach the Bronx, Andrew takes 30 + 8 = 38 hours to travel from Manhattan to the Bronx.
The answer: 38
Reverse engineering the question: Traveling from Manhattan to the Bronx, Andrew rides the subway for 10 hours, takes the train and rides for twice as much time as the subway ride, and then bikes the remaining distance for 8 hours. What's the total time he takes to reach the Bronx from Manhattan?


He has 3 * 4 = 12 trees. So he has 12 * 5 = 60 apples. So he sells the apples for 60 * .5 = $30.
The answer: 30
Reverse engineering the question:
John plants a plot of 3 trees by 4 trees. Each tree gives 5 apples. He sells each apple for $.5. How much money does he make, in dollars?
