Car rental agency A will rent a compact car for $40 per day and an additional charge of $0.20 per mile. Car rental agency B will charge only $0.16 per mile, but charges $51 per day. If Adam wanted to rent a car for four days, how many miles would Adam have to drive to make car rental agency B a better bargain?
m=miles driven
Agency A=$40+$0.20m
Agency B=$51+$0.16m
$40+$0.20m=$51+$0.16m Subtract ($40+$0.16m) from each side
$0.04m=$11 Divide each side by $0.04
m=275
ANSWER: Adam would have to average 275 miles per day or 1100 miles over four days for Agency B to be the better deal.
