There are 48 boxes x 24 erasers = 1,152 erasers. The student council will make 1,152 erasers x $0.75 = $864.
The answer: 864
Reverse engineering the question: The student council sells scented erasers in the morning before school starts to help raise money for school dances. The local bookstore donated 48 boxes of erasers. There are 24 erasers in each box. If the student council sells the erasers for $0.75 each, how much money will they make?


Reasoning and answer: Let's assume the total amount of money that Jane has is m. Since Jean has 3 times as much money as Jane, he has 3 * m = 3m. Combined, Jean and Jane have a total of m + 3m = $76. This evaluates to 4m = $76. The total amount of money that Jane has, represented by m, is m = $76 / 4. Jane has m = $19. Since Jean has three times as much money as Jane, Jean has 3 * $19 = $57.
The answer: 57
What was the question?
Question: Jean has three times as much money as Jane. They have a combined total of $76. How much money does Jean have?


If Alice has 60 pens, Clara 2 / 5 * 60 = 24 pens. The number of pens that Alice has more than Clara is 60 - 24 = 36. Since Alice is 20, and the number of pens that Alice has more than Clara is their age difference, Clara is 20 + 36 = 56 years old. In five years, Clara's age will be 56 + 5 = 61 years.
The answer: 61
Reverse engineering the question: The difference in the number of pens that Alice and Clara each have matches their age difference. Alice has 60 pens and Clara has 2/5 times as many pens as Alice. If Alice's age is 20 and Clara is older than Alice, calculate Clara's age in 5 years to come.


Reasoning and answer: The amoeba will divide into 1 * 2 = 2 amoebae after 2 days. The amoeba will divide into 2 * 2 = 4 amoebae after 4 days. The amoeba will divide into 4 * 2 = 8 amoebae after 6 days. The amoeba will divide into 8 * 2 = 16 amoebae after 8 days.
The answer: 8
What was the question?
Question: An amoeba reproduces by fission, splitting itself into two separate amoebae. An amoeba reproduces every two days. How many days will it take one amoeba to divide into 16 amoebae?


In one week he drove 18 + 26 + 20 + 20 + 16 = 100 miles. He is reimbursed $0.36 per mile of travel, and he travels 100 miles so he will receive .36 * 100 = $36.00.
The answer: 36
Reverse engineering the question: Lennon is a sales rep and is paid $0.36 in mileage reimbursement when he travels to meet with clients. On Monday he drove 18 miles. Tuesday he drove 26 miles. Wednesday and Thursday he drove 20 miles each day and on Friday he drove 16 miles. How much money will he be reimbursed?


The second cat meowed twice as frequently as the three meows per minute from the first cat, for a total of 2 * 3 = 6 meows per minute. The third cat meowed at one - third the frequency of the second cat, for a total of 6 / 3 = 2 meows per minute. Thus, combined, the three cats meow 3 + 6 + 2 = 11 times per minute. In five minutes, the three cats meow 5 * 11 = 55 times.
The answer: 55
Reverse engineering the question:
Three cats sat on a fence, meowing at the moon. The first cat meowed 3 times per minute. The second cat meowed twice as frequently as the first cat. And the third cat meowed at one-third the frequency of the second cat. What is the combined total number of meows the three cats make in 5 minutes?
