Question

You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed. Estimate the cost of having a 25 by 27 ft brick patio installed.

Answer 1

15 x 20 = 300 square feet

25x 27 = 675 square feet

It should cost a little over twice as much, a little over $4,550, since 675 is a little over 2 times 300

2275/300 = X/675

solve for X, the cost of 25x27

X = 2275 x 675/300 = 2274 x 27/12 = 2275 x 9/4 = 2.25 x 2275 = $5118.75
