A basic cellular package costs $30 per month for 60 minutes of calling, with an additional charge of $0.50/min beyond that time. The cost formula would be
C = 30 + 0.50(x β 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 $90, what is the maximum number of calling minutes you can use?
