Acar rental agency charges $25per day to rent a car and $12.95per day for a global positioning system (gps). customers are charged for their full tank of gas at $4.30per gallon. a car has a 19 gallon tank and a gps. write a rule for the total bill b as a function of the number of days d the car is rented. what is the bill for a 9 day rental?

b = $423.25

Step-by-step explanation:

cost of car rent per day = $25

Cost of GPS rent per day = $12.95

Cost of gas per gallon= $4.30

A car has 19 gallons and a GPS

The cost of gas for 19 gallons = 4.30 * 19

= $81.70

Total bill = b

Number of days = d

b = (25 + 12.95)d + 4.30*19

b = 37.95d + 81.70

When d = 9 days,

b = 37.95(9) + 81.70

b = 341.55 + 81.70

b = $423.25
