Problema Solution
twice last month Judy carter rented a car from a rental company and traveled around the southwest on business. The company rents its car for a daily fee, plus an additional charge per mile driven. Judy recalls that her first trip lasted 4 days, she drove 450 miles and the rental fee cost her $239.50. on her second business trip she drove 200 miles in 3 days, and paid $148.00 for rental. find the daily fee, and find the mileage charge
Answer provided by our tutors
let
d = the daily fee
m = the mileage charge (per mile)
First trip lasted 4 days and she drove 450 miles thus the cost can be written as
4d + 450m = 239.50
Second trip lasted 3 days and she drove 200 miles thus the cost can be written as
3d + 200m = 148
by solving the system of equations
4d + 450m = 239.50
3d + 200m = 148
we find
d = $34
m = $0.23

the daily fee is $34 and the company is charging $0.23 per mile (mileage charge).
