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?
If you were to write an equation for this it would be: 3x+15=51 (subtract 15 from both sides) 3x=36 (divide each side by 3) x=12 So on Monday, Wednesday and Friday she swims 15 laps.
