Answer: $25.2
Explanation:
First, let's find out how many miles Andrew walked in total by multiplying the number of laps by the length of each lap:
24 laps * 1/5 mile/lap = 24/5 miles = 4.8 miles
Now, we can find out how much money Andrew's dad donated by multiplying the total miles walked by the donation per mile:
4.8 miles * $5.25/mile = $25.2
Andrew's dad donated $25.2 to the school's art department.
