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 integaer greater than 1

Answer 1

C(x) = 5x + 2

This is because at 1 hour it only cost 7 dollars, so it should only have 2 added to the end.
