Question

A video rental company offers a plan that includes a membership fee of $7 and charges $4

for every DVD borrowed. They also offer a second plan, that costs $15 per month for
unlimited DVD rentals. If a customer borrows enough DVDs in a month, the two plans cost
the same amount. How many DVDs is that? What is that total cost of either plan?

Answer 1

The customer would have to rent two DVDs in order for the two amounts to be both $15

Explanation:

$7(the membership fee)-$15(unlimited plan)= $8 remaining

then you would divide 8 by four to see how many DVDs would have to be rented in order for the totals to be the same
