Your dining room (11ʹ× 13ʹ) has a hardwood floor discolored by uneven fading from sunlight exposure, and your living room (12ʹ× 12ʹ) has wall-to-wall carpet ruined by your aging dog. you have obtained some cost figures (all per square foot) from a local flooring store for refinished and new hardwood floors. the cost to purchase and install red oak flooring is $3.55 (includes tax), and labor is $1.50. refinishing costs the same $1.50. for new or old floors the labor/material/tax cost to apply a new light stain is $1.00 and two coats of polyurethane cost another $1.00. the store’s sales manager estimates that you should include a 5% wastage factor on the wood purchase. assume you will be removing and disposing of the carpet yourself without cost. estimate the total cost for both rooms.
