A basic cellular package costs $20/month for 60 minutes of calling with an additional charge of $0.20/minute beyond that time. The cost function C (a) for using a minutes would be . If you used 60 minutes or less, i.e. if if a < 60, then C (a) = 20 (the base charge). . If you used more than 60 minutes, i.e. (z - 60) minutes more than the plan came with, you would pay an additional $0.20 for each of those (z - 60) minutes. Your total bill would be C(x)=20+0.20 (z - 60). If you want to keep your bill at $50 or lower for the month, what is the maximum number of calling minutes you can use? The maximum calling minutes you can use is Number minutes.

A basic cellular package costs $20/month for 60 minutes of calling with an additional charge of $0.20/minute beyond that time. The cost function C (r) for using a minutes would be • If you used 60 minutes or less, i.e. if if a < 60, then C (x) = 20 (the base charge). . If you used more than 60 minutes, i.e. (r - 60) minutes more than the plan came with, you would pay an additional $0.20 for each of those (z - 60) minutes. Your total bill would be C(x)=20+0.20 (2- 60). If you want to keep your bill at $50 or lower for the month, what is the maximum number of calling minutes you can use?
