    A cellular phone company charges a $49.99 monthly fee for 600 free minutes. Each additional minute cost $.35. This month you used 750 minutes. How much do you owe?

    Calculate the excess minutes over the standard plan:
    Excess Minutes = 750 - 600
    Excess Minutes = 150

    Calculate additional cost:
    150 additional minutes * 0.35 per additional minutes = $52.50

    Add this to the standard plan cost of $49.99
    $52.50 + $49.99 = $102.49
