13. 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 remaining. write and solve
an equation to find out how much sheet metal
costs per square foot.

 is the required equation.

The  Per sq ft of sheet costs $ 27.31.

Step-by-step explanation:

The total amount of sheet purchased =  8.8 sq. ft

The amount of sheet used = 2. 1 sq ft.

The worth of remaining sheet = $183

Let us assume the  cost per sq ft of sheet = $x

Now, the remaining sheet =

Amount of total sheet purchased- Amount of sheet used

= 8.8 sq. ft - 2. 1 sq ft. = 6. 7 sq. ft

So, the worth of the remaining sheet 6.7 sq ft is $183.

⇒ Worth of 1 sq ft of sheet = $183 /6.7 sq ft

or,

or  x = $27.31

Hence, the  Per sq ft of sheet costs $ 27.31.
