<PRE><B>Question 849504</B>
The cost to rent a car for a certain number of hours is shown in the table. The total cost includes a fixed fee and an hourly rate.
Number of hours Cost
3 $89.25
6 $118.50
14 $196.50
A. Write an equation to model the data. Use y to represent the total cost and x to represent the number of hours the car is rented.
Equation:: y = fixed + h*x
------
Equations based on data:
f + 3h = 89.25
f + 6h = 118.50
f +14h = 196.50
-------------------------
Using the top two equations:
3h = 118.50-89.25
3h = 29.25
h = $9.25
B. What is the fixed fee charged to rent the car?
f + 3h = 89.25
f = 89.25-29.25 = $60.00
--------------------------------

c. What is the hourly rate charged to rent the car?
h = $9.25
