Question

At an airport, it costs $7 to park for up to one hour and $5 per hour for each additional hour. Let x

represent the number of hours parked. Write the function that models the cost, C(x), of parking x
hours, where x is an integer greater than 1. A:c(x)

Answer 1

C(X)=5(x-1)+7

Explanation:

because x-1 represents the fact that the first hour costs $7 and then x times 5 represents the fact that each hour after that costs $5
