Question

Sarah enrolled in a guitar class.

The enrollment fee was $25. She paid a total of $70 for the enrollment fee and three lessons. How much did each lesson cost?

Answer 1

The price was $15 per lesson.

Explanation:

We have to isolate the x, the cost per lesson. This is how we do so:

70-25 = 45, which is the cost for 3 lessons. Since she paid for enrollment plus three lessons, this takes care of the enrollment part, leaving just the 3 lessons cost, which is 45.

In order to isolate the cost per lesson, we have to divide 45 dollars by 3 lessons, which is 15 dollars per lesson.
