Anne Colton has a renovation business which uses painters to do custom paint jobs for house exteriors. She is trying to get a better idea of her cost structure to be able to bid on contracts as there has been new competition entering her neighbourhood from the downtown area. She has traditionally used the square footage of the houses she's worked on; but noticed that the amount of time taken also differed on the last 2 projects which had a lot of windows and doors, which requires a lot more preparation work. Information for her last 12 jobs are as follows: Total Cost Number of Windows & Doors 13 15 12 12 House Square Footage . 2,600 B 3,010 2,800 D 2,850 E 4,600 F 2,700 G 2,375 H 2,450 | 2,600 J 3,700 K 2,650 L 3,550 19 13 11 11 $3,335 3,742 3,100 3,150 4,700 3,225 2,920 2,836 2,945 4,112 3,210 3,965 IO 10 16 13 16 Required: 1) How much would Anne charge for a house with 3,300 square feet and 14 openings (windows and doors), based on: A. high-low method, based on square footage.
