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 $19 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?
first plan:
cost = 7 + 4v
second plan:
cost = 19
set 7+4v = 19 and solve for v
You must have a textbook from the 90's.
