@Mathematics Carl's cable company charges $55 for monthly service plus $4 for each pay-per-view movie. Teleview cable company charges $110 per month with no fee for movies. For what number of movies is the cost of Carl's cable company less than the cost of Teleview.

55+4x<110
4x<110/55
x<55/4
or, in a usable format
x<13.75      
round up 14
So, aslong as you dont buy more than 14 movies, carl's cable is cheaper.
