What's the trouble? Just write down what they told you:
b = 3.40*19 + (35.00+14.95)d
A car rental agency charges $35
per day to rent a car and $14.95
per day for a global positioning system (GPS). Customers are charged for their full tank of gas at $3.40
per gallon. A car has a 19
gallon tank and a GPS.
a) Write a function rule for the total bill b as a function of the days d the car is rented.
b) What is the bill for a 9 day rental?

Assuming that the person has to completely refill an empty tank:
35d + 19.95d + 19*3.40 = b
35d + 19.95d + 19*3.40 = b
