Question

Irma needs to rent a car for a business trip from Phoenix to San Jose (720 miles one way). She will drive round trip and will be gone a total of 8 days. The car rental company charges $65.00 per day and allows for 1,600 miles for Irmas's trip. There will be an additional charge of $0.24 per mile over the 1,600 miles allowed. How many total miles can she drive without exceeding her budget of $600.00?

Answer 1

The cost per day is $65 per day, the total cost for 8days will be:
8×65
=520
suppose that E is the number of miles she can drive without exceeding $600.
Thus
0.24×E+520=600
hence solving for E we get
0.24E=600-520
0.24E=80
hence
E=80/0.24
E=333.3333
E~333
