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?

To find the number of miles Erma can drive, you will write and equation and solve it to find the amount of miles that can be driven on $600 over the 1600 miles that are allowed.

Daily rate  + cost per mile over 1600 = total cost
(65 x 8) + 0.24m = 600
520 + 0.24m = 600
-520             -520
0.24m = 80
0.24       0.24
m = 333.33... miles

The maximum number of whole miles she can drive would be 1933 miles (1600 + 333).
