Given
A parking garage bases its prices on the number of hours a vehicle parks in the garage.
To find the pricing scheme the parking garage uses for vehicles.
From the graph, it is shown that the x-axis denotes the number of hours and the y-axis represents the cost in dollars.
Hence, for the first two hours, the cost will be 4 dollars, then from 2 to 6 hours the cost will be 2 dollars per hour, and the remaining hours after 6 hours will be 1 dollar.
Thus, the answer will be option c.
