Fiona earns 40 hours / week * $20 / hour = $800 / week. So she earns $800 / week * 4 weeks / month = $3200 / month. John earns 30 hours / week * $20 / hour = $600 / week. So he earns $600 / week * 4 weeks / month = $2400 / month. Jeremy earns 25 hours * $20 / hour = $500 / week. So he earns $500 / week * 4 weeks / month = $2000 / month. Overall their boss has to spend $3200 / month + $2400 / month + $2000 / month = $7600 / month.
The answer: 7600
Reverse engineering the question: In a car dealership, Fiona worked for 40 hours a week, John for 30 hours, and Jeremy for 25 hours. If the employees are paid $20 per hour, how much money does their boss spend paying all of them every month?


Reasoning and answer: For the nuts Adam paid 3 * $12 = $36. And for dried fruits Adam paid 2.5 * $8 = $20. So in total for his purchases Adam paid $36 + $20 = $56.
The answer: 56
What was the question?
Question: Adam bought 3 kilograms of nuts and 2.5 kilograms of dried fruits at a store. One kilogram of nuts costs $12 and one kilogram of dried fruit costs $8. How much did his purchases cost?


Mary has collected 5 * $600 = $3000. Scott therefore has $3000 / 3 = $1000. All together, they have raised $3000 + $1000 + $600 = $4600. They have therefore exceeded their goal by $4600 - $4000 = $600.
The answer: 600
Reverse engineering the question: Scott, Mary, and Ken committed to raising $4,000 for their local children’s cancer hospital. Right now, Mary’s collection is five times what Ken has, but three times Scott’s funds. If Ken has $600, by how much have the three exceeded their goal?


Reasoning and answer: He needs 12 / 6 = 2 rungs per foot. So he needs 50 * 2 = 100 rungs. Each rung is 18 / 12 = 1.5 feet. So he needs 1.5 * 100 = 150 feet.
The answer: 150
What was the question?
Question: James wants to build a ladder to climb a very tall tree. Each rung of the ladder is 18 inches long and they are 6 inches apart. If he needs to climb 50 feet how many feet of wood will he need for the rungs?


William spends 4 + 7 + 4 + 9 = 24 minutes washing a normal car. He washed 2 normal cars, so he spent 24 * 2 = 48 minutes on the normal cars. He took twice as long as one car for the SUV, so he took 24 * 2 = 48 minutes on the SUV. Thus, William spent 48 + 48 = 96 minutes washing all the vehicles.
The answer: 96
Reverse engineering the question: William washes cars as a side job. He typically spends 4 minutes washing a car’s windows, 7 minutes washing the car body, 4 minutes cleaning the tires, and 9 minutes waxing the car. This morning he washed 2 normal cars and one big SUV, which took twice as long as a normal car. How many minutes did William spend washing all the vehicles?


Amoli = 42 * 3 = 126 miles. Anayet = 61 * 2 = 122. Together = 126 + 122 = 248 miles. 369 - 248 = 121 miles. They still have 121 miles to travel.
The answer: 121
Reverse engineering the question:
Amoli and Anayet must travel 369 miles together. Amoli drove 42 miles an hour for 3 hours and Anayet drove at 61 miles an hour for 2 hours. How many miles do they still need to travel?
