Question 1114389: Greg rented a truck for one day. There was a base fee of $11.00, and there was an additional charge of 9 cents for each mile driven. The total cost, C (in dollars), for driving x miles is given by the following function. C(x) = 11.00+ 0.09x. What is the total rental cost if Greg drove 30 miles?

You can put this solution on YOUR website!
You only have two variables.
C(x) for cost
x for miles driven

----------------------------------------------------------
What is the total rental cost if Greg drove 30 miles?
-----------------------------------------------------------

What did that mean?
C(x), being asked for
x=30

What next step?
C%2830%29=11%2B0.09%2A%2830%29
