Question

Susan rented a truck for one day. There was a base fee of $12.25, and there was an additional charge of 25 cents for each miles driven.The total cost, C ( in dollars), for driving x miles is giving by the following
C=0.25x+12.25
What is the total rental cost if Susan drove 30 miles?

Answer 1

To find the total rental cost if Susan drove 30 miles, we need to substitute 30 for x in the equation C=0.25x+12.25.

C = 0.25(30) + 12.25
C = 7.5 + 12.25
C = 19.75

Therefore, the total rental cost if Susan drove 30 miles is $19.75.
