Samantha is deciding between two different movie streaming sites to subscribe to. Plan A costs $18 per month plus $1 per movie watched. Plan B costs $14 per month
plus $2 per movie watched. Let A represent the monthly cost of Plan A if Samantha
watches 2 per month, and let B represent the monthly cost of Plan B if Samantha
watches x movies per month. Graph each function and determine the number of
monthly movies watched, 2, that would make the two plans have an equal monthly
cost.
