An interior designer is redecorating a room that is 23 feet long by 16 feet wide by 8 feet high. At one end of the room is a door that is 6 feet 6 inches high and 4 feet wide. One of the walls contains 2 windows, each of which is 2 feet wide by 2 feet 6 inches high. There are no other windows, doors, or even a closet. a) How much will it cost to carpet the floor if the carpet sells for $18.00 a square yard? Assume we can buy exactly as much carpet as we need. $ b) How much will it cost to wallpaper all four walls if wallpaper costs $0.75 per square foot? Assume we can buy exactly as much wallpaper as we need. $ (Hint: It's generally considered a bad idea to cover a door or windows with wallpaper.) c) How much will it cost to paint the ceiling using paint that sells for $25 per gallon if a quart of paint will cover 88 square feet? Assume we can buy exacity as much paint as we need. $ d) What will be the cost of the entire project? $ e) Projects rarely finish within the projected budget. To cover the hidden cost of surprises, add an extra 15% to the cost of this project. $
