Susan is planning to replace the carpet in her living room. Her living room measures 15ft long and 10 feet wide. How many square feet of carpet will she need? Also, at $3.99 a square foot, how much will it cost her?

Solution: Use the formula Area = length x width. 15ft x 10 ft = 150 square feet. At $3.99 per square foot, it will cost Susan $598.50.
