derp belongs to a movie club in which he pays an annual fee of $39.95 and then rents DVDs for $0.99 each. in one year, derp spent $54.80. how many DVDs did he rent?

Answer 1

Let x = the number of DVDs rented.

 

Cost = ($0.99)x + $39.95

 

The cost is given as $54.80:

 

$54.80 = ($0.99)x + $39.95

 

Solve for x.
