Round your answer to the nearest dollar.

Answer 1

Answer: $1,775

Explanation:

We can use a proportion to estimate the cost of having a 13 ft by 18 ft brick patio installed, based on the cost of a 15 ft by 20 ft patio:

(cost of 13 ft by 18 ft patio) / (cost of 15 ft by 20 ft patio) = (area of 13 ft by 18 ft patio) / (area of 15 ft by 20 ft patio)

The area of the 13 ft by 18 ft patio is 13 x 18 = 234 sq ft, and the area of the 15 ft by 20 ft patio is 15 x 20 = 300 sq ft.

So,

(cost of 13 ft by 18 ft patio) / ($2,275) = 234 / 300

Solving for the cost of the 13 ft by 18 ft patio, we get:

cost of 13 ft by 18 ft patio = ($2,275) x (234 / 300) = $1,775.25

Rounding to the nearest dollar, the estimated cost of having a 13 ft by 18 ft brick patio installed is $1,775.
