If each bulb uses 60 watts each day, the 40 bulbs that Allyn has uses 60 * 40 = 2400 watts of power each day. In June, with 30 days, the bulbs will use 30 * 2400 = 72000 watts of power. If Allyn is charged an electricity bill of twenty cents per power watt used, in June she will pay 72000 * $0.20 = $14400.
The answer: 14400
Reverse engineering the question: A sixty bulb watt uses 60 watts of power each day. If Allyn has 40 such bulbs in his house and pays an electricity bill of twenty cents per power watt used, calculate Allyn's total monthly expenses on electricity in June.
Reasoning and answer: There are 80 cherries in a pound and she needs 3 pounds to make a pie so she needs 80 * 3 = 240 cherries. It takes her 10 minutes to pit a unit of 20 cherries. She has 240 / 20 = 12 units of cherries to pit. It takes 10 minutes to pit a unit of cherries and she has 12 units so it will take her 10 * 12 = 120 minutes. 60 minutes are in 1 hour and it takes her 120 minutes so that's 120 / 60 = 2 hours.
The answer: 2

Question: To make a cherry pie, Veronica needs 3 pounds of pitted cherries. There are 80 single cherries in one pound of cherries. It takes 10 minutes to pit 20 cherries. How many hours will it take Veronica to pit all the cherries?
After using the coupon, the final price comes to 67 - 4 = 63 dollars. With three people, they each need to pay 63 / 3 = 21 dollars each.
The answer: 21
Reverse engineering the question: Sarah, Mary, and Tuan decided to go to the restaurant for a meal. They decided to split the cost of the meal evenly. If the total price of the meal comes to $67 and they have a coupon for $4, how much does each person need to contribute to the bill?
Reasoning and answer: On the second day, the company paved 4 * 2 - 1 = 7 miles. The company has 16 - 7 - 4 = 5 miles of road remaining to pave. They will need 3 * 5 = 15 truckloads of asphalt to pave 5 miles of road. For 15 truckloads, they will need 15 * 2 = 30 bags of gravel. Thus, the company will need 30 / 5 = 6 barrels of pitch to finish the road on the third day.
The answer: 6
What was the question?
Question: A roadwork company is paving a newly constructed 16-mile road. They use a mixture of pitch and gravel to make the asphalt to pave the road. Each truckloads of asphalt uses two bags of gravel and five times as many bags of gravel as it does barrels of pitch to make. It takes three truckloads of asphalt to pave each mile of road. The company paved 4 miles of road on one day, then one mile less than double that on the second day. How many barrels of pitch will the company need to finish the remaining road on the third day?
The number of times Jason goes to the library per week is 4 * 2 = 8 times. The number of times he goes to the library in 4 weeks is 8 * 4 = 32 times.
The answer: 32
Reverse engineering the question: Jason goes to the library 4 times more often than William goes. If William goes 2 times per week to the library, how many times does Jason go to the library in 4 weeks?
From Monday to Tuesday, Nico reads a total of 20 + 12 = 32 pages. On Wednesday, he read a total of 51 - 32 = 19 pages.
The answer: 19
Reverse engineering the question:
Nico borrows 3 books from the library on Monday. On Monday, he reads the first book with a total of 20 pages. On Tuesday, he reads the second book with a total of 12 pages. On Wednesday, he reads the third book. If he has read a total of 51 pages from Monday to Wednesday, how many pages did he read on Wednesday?
