Question

Audrey has $120 dollars to spend on a tennis racket and lessons. The racket costs $45 and the lessons cost $15 dollars per hour. Define a variable. The write and solve an equation to find how many hours of lessons she can afford.

Answer 1

45+15x=120
15x is the variable since it is a reoccurring fee.

Answer 2

x = how many hours she can afford
120 = 45 + 15x
first you subtract 45 from both sides
75 = 15x
divide both sides by 15
5 = x

so audrey can afford 5 hours of lessons

i hope this helps!!
