a contractor buys 8.2 square feet of sheet metal. she used 2.1 square feet so far and has 183 worth of sheet metal remaning write and solve an equation to find out how much sheet metal cost per square foot

Step-by-step explanation:

8.2 - 2.1 = 6.1

$183 / 6.1 = $30 for one sq. ft.

Just to make sure:

8.2 * $30 = $246

$246 / 8.2 = $30

So the contractor originally had 8.2 sq ft of metal and it was worth 246 so to find how much it cost you have to divide 8.2 and 246 which is 30 per sq ft.
