Audrey has $120 to spend on a tennis racket and lessons. the racket costs $45 and lessons are $15 per hour. write and solve an equation to find many hours of lessons can audrey afford.

First find 120-45 and see what you have left. Then get that number and divide it by 15 to get the answer.

120-45=75

75÷15=5

Audrey can only afford 5 lessons
