number of DVD rented .... x
so when is 5x + 10 = 40 ?
solve for x, then sub into 5x+10
(time to update that textbook, DVD rental outlets closed years ago)
A video rental company offers a plan that includes a membership fee of $10 and charges $5 for every DVD borrowed. They also offer a second plan, that costs $40 per month for unlimited DVD rentals. If a customer borrows enough DVDs in a month, the two plans cost the same amount. What is that total cost of either plan?
