Question 800982: Abel rented a car from Sunshine Car Rentals. He was charged $85 per day and $0.50 per mile. He rented the car for 3 days and paid a rental car cost of $375. How many miles did he drive the car? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! C(d) cost of rental per day
C(d) = 85 +0.5x
for 3 days 3(85+0.50x)
3(85+0.50x)=375
/3
85+0.50x=125
0.50x=125-85
0.50x=40
x= 40/0.50
x= 80 miles
