Bonny's truck has a fuel tank which holds 50 gallons, and she typically drives 425 miles on a full tank. she has added a second tank, which holds 30 gallons. to figure how far she can go between fill-ups now, she multiplies 50 x 425, then divides by 30, to get 708.3 miles. is this correct?
a) yes.
b) no; she should have multiplied 425 by 30 + 50.
c) no; she should have divided 425 by 50, then multiplied by 80.
d) no; she should have divided 50 by 30, then multiplied that by 425.
