    A. No, the estimate should be higher

    Step-by-step explanation:

    To determine the maximum number of gallons of fuel the car can consume, we express this as;

    Maximum miles driven=highest consumption per gallon*Maximum gallons

    where;

    Maximum miles driven per person=64 mile

    Maximum miles driven=64*4=256 miles

    highest consumption per gallon=24.56 miles per gallon

    Maximum gallons=g

    replacing;

    256=24.56*g

    24.56 g=256

    g≥256/24.56=10.42 gallons

    g≥10.42 gallons

    No, the estimate should be higher
