Question

Best Rentals charges a daily fee plus a mileage fee for renting its cars. Barney was charged $123.00 for 3 days and 300 miles, while Mary was charged $216.00 for 5 days and 600 miles. What does Best Rental charge per day, for mileage?

Answer 1

Set up a 2-variable system of equations, using d for days and m for miles. Barney's equation is 3d + 300m= 123 and Mary's is 5d + 600m = 216. Solve using elimination.
