Answer:
14.5*29=420.5 miles for a full 14.5-gallon tank.
7.25-gallons is what is left in a half tank.
105.125 miles can be driven on a quarter tank.
if the low milage alert comes on at 50 miles left they have 1/9 of the tank left with gas.
if the low milage alert comes on at 50 miles left he was 1.724 gallons of gas left.
It would cost $30.28 to get the tank back to a full 14.5 gallons.
