Question

Ella swims four times a week at her club's pool. She swims the same number of laps on Monday, Wednesday, and Friday, and 15 laps on Saturday. She swims a total of 51 laps each week. How many laps does she swim on Monday?

Answer 1

12 laps on Monday 51=15+3L. 51-15=15-15+3L. 36=3L. 36÷3=3÷3L. 12=L
L= Laps

Answer 2

So assuming she swims the same on Monday, Wednesday, and Friday, as well as 15 on saturday, We can essentially set up an equation.

(51-15)/3

(36)/3

She swims 12 laps On Monday.
