Question 1124911: A basic cellular package costs $20 per month for 60 minutes of calling, with an additional charge of $0.20/min beyond that time. The cost formula would be C = 20 + 0.20(x − 60), where C is the cost measured in dollars and x is the number of calling minutes used. If you cannot have a bill greater than $50, what is the maximum number of calling minutes you can use? Answer by josgarithmetic(39618) (Show Source):
