if the daily fee is d, and the mileage fee is m,
3d+300m = 120
5d+600m = 210
$30/day + $.10/mile
3d+300m = 120
5d+600m = 210
$30/day + $.10/mile
We have two customers, Barney and Mary, with different rental periods and mileage.
Barney rented a car for 3 days and drove 300 miles. He was charged $120.
Mary, on the other hand, rented a car for 5 days and drove 600 miles. She was charged $210.
Now, let's find the daily fee and mileage fee charged by Best Rentals.
To find the daily fee, we can divide the total charge by the number of days.
Barney's daily fee = $120 / 3 = $40 per day
Mary's daily fee = $210 / 5 = $42 per day
Now, we can find the mileage fee per mile.
Barney's mileage fee - $120 - ($40/day x 3 days) = $120 - $120 = $0
Barney was not charged separately for the mileage since it's mentioned that he drove 300 miles, but there's no specific mileage fee given.
Mary's mileage fee - $210 - ($42/day x 5 days) = $210 - $210 = $0
Similar to Barney, Mary was also not charged separately for the mileage since it's mentioned that she drove 600 miles, but there's no specific mileage fee given.
Hence, according to the given information, Best Rentals does not charge separately for mileage. They charge a fixed daily fee per day.
Therefore, the daily fee is $40 per day for Best Rentals, and there is no separate charge for mileage mentioned.
