ANSWER: $2,563
EXPLANATION: We would use the areas of these patios to find the price per square foot. 15 times 20 = 300square feet. The price of this patio was $2,275, so we would divide 2,275 by 300 to find the price per square foot. We get $7.58. Then we find the area of the second patio. 13 times 26 is equal to 338 square feet. 338 times $7.58 is equal to $2,563.17. Rounded to the nearest dollar would be $2,563.
