    We divide 100 miles by each car ... 100/25 = 4 gallons on that car

    100/32 = 3.125 gallons on this one

    subtract the two answers 4 - 3.125 and we get a savings of. 875 gallons on 100 miles.

    The answer is B ...875 gallons

    25/1=100/x

    25x=100

    x=100/25=4 gallons

    32/1=100/x

    32x=100

    x=100/32

    x=3.125 gallons

    4-3.125=0.875 gallons
