Which graph models the piecewise function for the given situation?
A.
The piecewise function represents the number of hours on the x-axis and the number of boxes on the y-axis. The function starts from (0, 0), (3, 240), (5, 240), and (9, 280).
B.
The piecewise function represents the number of hours on the x-axis and the number of boxes on the y- axis. The function starts from (0, 0), (4, 60), (6, 60), and (9, 320).
C.
The piecewise function represents the number of hours on the x- axis and the number of boxes on the y- axis. The function starts from (0, 0), (3, 240), (5, 240), and (9, 320).
D.
The piecewise function represents the number of hours on the x-axis and the number of boxes on the y-axis. The function starts from (0, 0), (3, 240), (7, 320), and (9, 320).
