The Magic Carpet charges $90 for installation and $9 per square yard of carpeting. If the total cost to carpet an office is $810, how many square feet is the office?

Step-by-step explanation:

Step one:

given data

charges=$90

installation=$9 per square yard

total cost of installation= $810

let x represents the number of square feet

Step two:

The expression for the installation cost is given as

810=9x+901

solve for x, collect like terms

810-90=9x

720=9x

divide both sides by 9 we have

x=720/9

x=11.11 square yard
