Reasoning and answer: They need to buy 180 / 30 = 6 boxes. So the cost is 6 * 40 = $240.
The answer: 240
What was the question?
Question: A convenience store sells 180 gallons of soda a week. They buy syrup boxes that can make 30 gallons of soda, and each box costs $40. How much do they pay for syrup a week?
At 60 minutes per hour, the sunset was 2 * 60 = 120 minutes long. The sky changes color every 10 minutes, so it turned 120 / 10 = 12 colors over the summer sunset.
The answer: 12
Reverse engineering the question: Every ten minutes during sunset, the sky changes to a new color. How many colors did the sky turn over the two hours of a long summer sunset if each hour is sixty minutes long?
Reasoning and answer: Carmen earned 3 * $4 = $12 at the green house. She earned 2 * $3.50 = $7 for the mints. She earned $7 + $5 = $12 at the yellow house. She earned 9 * $2 = $18 at the brown house. So, Carmen earned a total of $12 + $12 + 18 = $42.
The answer: 42

She sells three boxes of samoas to the green house for $4 each; two boxes of thin mints for $3.50 each and one box of fudge delights for $5 to the yellow house; and nine boxes of sugar cookies for $2 each to the brown house.

Katelyn made 49 + 47 = 96 sandwiches. Chloe made 96 / 4 = 24 sandwiches. Billy, Katelyn, and Chloe made 49 + 96 + 24 = 169 sandwiches in all.
The answer: 169
Reverse engineering the question: Billy made 49 sandwiches; Katelyn made 47 more than that. Chloe made a quarter of the amount that Katelyn made. How many sandwiches did they make in all?
Reasoning and answer: He buys 20 * 60 = 1200 minutes of music a month. So that is 1200 / 3 = 400 songs. That means he pays 400 * .5 = $200 a month. So it comes out to 200 * 12 = $2400 a year.
The answer: 2400
