This is definitely one of my weaker areas in math, so any help is appreciated, thanks in advance.
Kim plans to paint the floor and outside walls of a playhouse that her dad built for her. She also wants to shingle the roof. The house is 9 feet long, 7 feet wide and 8 feet high at the peak, and the walls are 6 feet high. There are four windows (2' by 2' each) one door (5' by 2'). Paint is sold in 4L cans at $24.99 each, and shingles cost $34.99 per bundle. One bundle of shingles covers about 25 square feet, and one 4L can of paint covers 125 square feet. She also needs to buy a brush for $6.99, a roller brush for $10.95 and shingle nails for $4.00.
A. Draw a sketch of the house showing front and side views. Be sure to show where you would locate the door and the windows.
B. Determine the area to be painted, and also the cost of painting if she applies two coats of paint.
C. Determine the area to be shingled, and the total cost of shingling.
D. How long will she spend painting if she can paint 25 square feet in 15 minutes?
E. Kim decides to build a small 6' by 5' deck for the house using boards that are 4" wide and cost $0.35 per foot. What is the cost of the deck? (Her dad has given her some materials to build the base of the deck, and she uses the 4" boards to cover the base.)
F. What is Kim's total cost of painting, shingling and deck building? Be sure to include PST and GST at 7% each.
