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.
