[Question]The school is hosting a race after school. The winner is the person who runs the most laps around the school in 12 minutes. One lap around the school is 100 meters. The winner is awarded a gift certificate equal to $3.5 for every one hundred meters they run. The winner runs 24 laps around the school. On average, how much did they earn per minute?
[Answer]They ran 2,400 meters because 24 laps x 100 m / lap = 2400 m. They ran 200 meters per minute because 2400 m / 12 min = 200 m / min. For every minute they ran they earned an average of $7 because $3.5 / 100m x 200 m / min = $7 / min. The answer is 7.

[Question]Nick has 60 cans. Each can takes up 30 square inches of space before being compacted and 20% of that amount after being compacted. How much space do all the cans take up after being compacted?
[Answer]
First find the total amount of space the cans take up before being compacted: 60 cans * 30 sq in / can = 1800 sq in. Then multiply that amount by the percentage of space they take up after being compacted: 1800 sq in * 20% = 360 sq in. The answer is 360.
