Justin is planning to paint a building whose dimensions are shown below. The front of the building has a door measuring 54 in by 80 in. The left and right sides of the building each have 2 windows measuring 7ft by 4 ft each. The back of the building has no window or door.

a) Assuming the roof, windows, and door require no paint, what is the area in square feet that needs paint ? (Do not round any intermediate computations and give your answer as a whole number.)

b) Justin will use paint that is sold in cans. Each can contains enough paint to cover 240 ft^2. Assume Justin doesn't have any paint yet and he can't buy partial cans. How many cans will he need to buy in order to paint the building?

c) If each can costs $35.50, how much will Justin need to spend on paint ?
