Reasoning and answer: Bill gives each of his children 3 apples, so since he has two children this is 3 * 2 = 6 apples. Jill bakes 2 apple pies, using 10 apples each so this means she uses 10 * 2 = 20 apples. In total, this means 20 + 6 = 26 apples were used. Since Bill began with 50 apples, this means there are 50 - 26 = 24 apples remaining.
The answer: 24

The mileage cost for the first apartment will be 31 * 20 * 0.58 = $359.60. This makes the total monthly cost of the first apartment 359.60 + 800 + 260 = $1419.60. Similarly, the mileage cost for the second apartment will be 21 * 20 * 0.58 = $243.60. Thus, the total monthly cost of the second apartment is 243.60 + 900 + 200 = 1343.60. Therefore, the difference in total monthly costs is 1419.60 - 1343.60 = $76.
The answer: 76
Reverse engineering the question: A man is trying to maximize the amount of money he saves each month. In particular, he is trying to decide between two different apartments. The first apartment costs $800 per month in rent and will cost an additional $260 per month in utilities. The second apartment costs $900 per month and will cost an additional $200 per month in utilities. The first apartment is slightly further from the man's work, and the man would have to drive 31 miles per day to get to work. The second apartment is closer, and the man would only have to drive 21 miles to get to work. According to the IRS, each mile a person drives has an average cost of 58 cents. If the man must drive to work 20 days each month, what is the difference between the total monthly costs of these two apartments after factoring in utility and driving-related costs (to the nearest whole dollar)?


Reasoning and answer: Christian just mowed 4 yards at $5.00 each so he made 4 * 5 = $20.00. Sue just walked 6 dogs at $2.00 each so she made 6 * 2 = $12.00. Christian had $5.00 saved and just made $20.00 while Sue had $7.00 saved and just made $12.00 so together they had 5 + 20 + 7 + 12 = $44. The perfume cost $50.00 and they had $44.00 so they needed to make 50 - 44 = $6.00 more dollars.
The answer: 6

Roque takes 2 * 3 = 6 hours a week to walk to work. Roque takes 6 * 2 = 12 hours a week to walk to and from work. Roque takes 1 * 2 = 2 hours a week to bike to work. Roque takes 2 * 2 = 4 hours a week to bike to and from work. In total, Roque takes 12 + 4 = 16 hour a week to go to and from work.
The answer: 16
Reverse engineering the question: It takes Roque two hours to walk to work and one hour to ride his bike to work. Roque walks to and from work three times a week and rides his bike to and from work twice a week. How many hours in total does he take to get to and from work a week with walking and biking?


Reasoning and answer: First, we add the two types of days together to find 10 + 10 = 20 days in total between the two types. We then divide this number in half to find Mark's remaining number of days, getting 20 / 2 = 10 days remaining. Since each day counts as 8 hours, we multiply 10 * 8 = 80 hours' worth of days remaining for Mark.
The answer: 80
