Algebra 1 story problem (PLEASE solve QUICKLY)

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

15.50 = 5 + 1.5x, x being movies rented out that month.

 

15.50 - 5 = 1.5x

 

10.5 = 1.5x

 

x = 10.5/1.5

 

x = 7
