t 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 28 ft brick patio installed.

Answer 1

15 bt 20 =300 ft^2 costing 2275

which is 2275/300 per ft^2 = $7.58 1/3

25 by 28 would cost (25)(28)(2275/300) = 2275(7/3) = $5308.33
