Question

Ann and Joe’s father donated $3 for every lap they swam in a swim-a-thon. Ann swam 21 laps, and Joe swam 15 laps. Find the amount of money their father donated.

Answer 1

Step 1: Find the total number of laps that Ann and Joe did.

Ann: 21 laps
Joe: 15 laps
Total: 21 laps + 15 laps = 36 laps

Step 2: Multiply each lap swam by $3.

36 x $3 = $108

Their father donated $108.
