8. Wayne's Windows charges a $40 flat fee to cover travel and expenses plus $25 per hour

to wash windows at one building. A function c (h) can relate the cost of washing a

building's windows and the number of hours, h, that it takes to wash them.

Wayne's Windows can wash one window pane every 3 minutes. A function h (p) can

relate the hours that are needed to wash windows and the number of panes, p, in the

windows.

Which composition of functions describes the cost, c (h (p)), of washing p panes at one

building?

A. c (h (p)) = 40 + 0.05p

B. c (h (p)) = 40 + 1.25p

C. c (h (p)) = 40 + 28p

D. c (h (p)) = 40 + 115p
