A car rental agency charges ​$32 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 ​$4.10 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 12 day​ rental?

Answer 1

a)`$(46.95d+77.90)`

b)`$641.30`

Explanation:

you pay $32 a day rent and $14.95 a day for the GPS so you pay $46.95 a day for both. $4.10 a gallon for 19 gallons is $77.90

So for `d` days you would pay `$(46.95d+77.90)`

For 12 days `=>$(46.95xx12+77.90) =$(563.40+77.90)`

`=> = $641.30`
