Question

An online movie club offers a membership for $5 per month. Members can rent movies for $1.50 per rental. A member was billed $15.50 one month. Write and solve an equation to find how many movies the member rented.

Answer 1

5 + 1.50x = 15.50
(Minus five on both sides)
-5 -5
1.50x = 10.50
(Divide 1.50 on both sides)
÷1.50 ÷1.50
x = 10 movies
