Carpet stain protector costs $0.65 per square yard to apply. How much will it cost to apply the protectant to a 16-foot x 18-foot carpet?
Detailed Explanation
To determine the number of square yards to be protected, multiply 16 feet by 18 feet to determine the number of square feet, 288. Then divide 288 by 9 to convert square feet to square yards (1 square yard = 3 feet × 3 feet = 9 square feet). Multiply the quotient, 32 square yards, by the cost of protection per square yard, 0.65, to get the correct answer, 20.80. Remember to perform all the steps in a calculation.
