The Garcia family is trying to decide between installing cable TV or purchasing a DVD player and renting movies. The Garcias need to compare the cost of each option over several months in order to make an appropriate decision.

Cable TV has a one-time installation charge of $54 and a monthly charge of $48

A DVD player costs $119 and the Garcias will spend $36 per month in DVD rentals

Which plan is better (less expensive) for the Garcia family?
