    Estimate = $34.50

    Actual charge $33.47

    Step-by-step explanation:

    To estimate, we round the numbers

    9.7 gallons rounds to 10 gallons

    10 gallons * 3.45 per gallon = 34.50

    This is an overestimation

    The actual charge

    9.7 * 3.45 = 33.465

    We round to the nearest cent

    33.47
