Best Rentals charges a daily fee plus a mileage fee for renting its cars. Barney was charged $120 for 3 days and 300 miles, while Mary was charged $210 for 5 days and 600 miles. What does Best Rental charge per day and per mile?

if the daily fee is d, and the mileage fee is m,

3d+300m = 120
5d+600m = 210

$30/day + $.10/mile
