First we have to find cost of gas.

12*3.80=45.6$ - it should be added to total cost

Cost for one day is 29+13.95=42.95$

We assume that d is number of days the car is rented.

So:

total cost=42.95d+45.60

Now we can find bill for a 9 day rental by just putting 9 as d.

total cost=42.95*9+45.60=432.15$ - result
