    Answer: 71.1minutes

    Step-by-step explanation:

    From the question, we were given monthly cost of calls and amount of call per minute.

    To express the monthly cost in terms of minutes of call time will be:

    Monthly cost = call per minute x f

    Let minutes of call time be f

    13.5 = 0.19 x f

    13.5 = 0.19f ... divide both sides by 0.19

    f = 13.5 / 0.19

    f = 71.1 minutes
