m = the charge per mile
Jon rented a car from a company that charged a daily rental fee and a mileage charge. He rented the car for 6 days and drove 300 miles and was charged $285.
6d + 300m = 285
His friend Amanda later rented the same car for 7 days and drove 260 miles and was charged $310.
7d + 260m = 310
by solving the system of equations
6d + 300m = 285
7d + 260m = 310
we find
d = $35
m = $0.25
