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


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.
