Josh rented a truck for one day there was a base fee fee of $12 and there was additional charge of 8 cents for each mile driven the total cost (c) for driving x miles is given by the following function

C(x)=12.00+0.08x

what is the total rental cost if Josh drive 20 miles?
​

Answer 1

$13.60

Explanation:

You want to evaluate the rental cost function C(x) = 12.00 +0.08x for x = 20.

Evaluation

Put the value for x where x is in the cost function and do the arithmetic.

C(x) = 12.00 +0.08x

C(20) = 12.00 +0.08·20 = 12.00 +1.60

C(20) = 13.60

The total rental cost if Josh drives 20 miles is $13.60.
