He has 5 * 12 = 60 boxes of matches. That means he has 60 * 20 = 1200 matches.
The answer: 1200
Reverse engineering the question: James has 5 dozen boxes of matches. Each box contains 20 matches. How many matches does James have?


Reasoning and answer: He spends 5 minutes ironing his shirt and 3 minutes ironing his pants so that's 5 + 3 = 8 minutes. He does this every day for 5 days so that's 5 * 8 = 40 minutes. After 4 weeks, Hayden has spent 4 * 40 = 160 minutes ironing his clothes.
The answer: 160
What was the question?
Question: Before work, Hayden spends 5 minutes ironing his button-up shirt and 3 minutes ironing his pants. He does this 5 days a week. How many minutes does he iron over 4 weeks?


In the second week, Hannah will save $4 x 2 = $8. In the third week, she will save $8 x 2 = $16. In the fourth week, she will save $16 x 2 = $32. Her total savings for a month will be $4 + $8 + $16 + $32 = $60. Hannah needs to save $80 - $60 = $20 in the fifth week.
The answer: 20
Reverse engineering the question: Hannah wants to save $80 for five weeks. In the first week, she saved $4 and she plans to save twice as much as her savings as the previous week. How much will she save in the fifth week to reach her goal?


Reasoning and answer: If Judson paid $500, Kenny contributed 20 / 100 * $500 = $100 more than Judson. In total, Kenny contributed $500 + $100 = $600. Kenny and Judson contributed a total of $600 + $500 = $1100. If Camilo contributed $200 more than Kenny, then he contributed $600 + $200 = $800. The total amount of money the three contributed for the house painting is $1100 + $800 = $1900.
The answer: 1900
What was the question?
Question: Judson, Camilo, and Kenny decided to contribute money to paint their house. Judson contributed $500, Kenny contributed 20% more money than Judson, and Camilo contributed $200 more than Kenny. How much was the cost of painting the house?


If a monkey swings 1.2 meters a second then a monkey can swing 1.2 meters / second * 60 seconds / minute = 72 meters in a minute. If a monkey swings 72 meters in a minute then a monkey can swing 72 meters / min * 30 minutes = 2,160 meters in 30 minutes.
The answer: 2160
Reverse engineering the question: A monkey swings from branch to branch at an average distance of 1.2 meters per second. How far will a monkey swing in meters if it consistently swings from branches for 30 minutes?


He uses 3 detergent pods a week and there are 52 weeks in a year, so he uses 3 * 52 = 156. His detergent has 39 pods per pack and he needs 156 pods, so he will need 156 / 39 = 4 packs of detergent pods.
The answer: 4
