Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
24 laps around the school is 2,400 meters.
For every 100 meters run, the winner was awarded $3.5, so they earned $3.5/100 * 2400 = $<<3.5/100*2400=84>>84
The winner earned $84 / 12 minutes = $<<84/12=7>>7 per minute
