Your cell phone carrier is offering you a new iPhone 12 for $800 with a $60 monthly plan. The total cost can then be defined by the function C(x)=800+60x, where represents the number of months you own the phone. The average monthly cost will depend on how many months you own the phone and can be found with the function A(x) = (800+60x)/x. 1. How long will it take for the average monthly cost to be $70?
