Question

Lashonda rented a truck for one day. There was a base fee of $13.50, and there was an additional charge of 5 cents for each mile driven. The total cost, C (in dollars), for driving x miles is given by the following function.

C(x)= 0.05x + 13.50
What is the total rental cost if lashonda drove 30 miles

Answer 1

Replace x in the equation with 30 miles:

C = 0.05(30) + 13.50

C = 1.50 + 13.50

C = 15.00

It cost $15.00
