Problema Solution
Davis Rent- A- Car charges a fixed amount per weekly rental plus a charge for each mile driven. A one- week trip of 520 miles costs $250, and a two week trip of 800 miles costs $440. Find the weekly charge and the charge for each mile driven.
Answer provided by our tutors
let 'm' represent the charge per mile and 'w' represent the weekly rate
we have these two equations for cost:
250 = w + 520m
440 = 2w + 800m
solving this system we have:
m = 0.25
w = 120
the weekly charge is $120 and the charge per mile is $0.25
