A contractor bought 7.6 ft2 of sheet metal. He has used 2.3 ft2 so far and has ​$95.40 worth of sheet metal remaining. The equation 7.6x−2.3x=95.4 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square​ foot?
Sheet metal costs $? per square foot

Answer 1

he bought 7.6 ft2 of sheet metal
He used 2.3 ft2

7.6x−2.3x= $95.40

simplify

5.3x = $95.40

divide by 5.3 to get x by itself

x = 18

so each sheet of metal costs $18.00 per square foot.
