Question

A contractor bought 7.6 ft2 of sheet metal. He has used 3.7 ft2 so

far and has $70.20 worth of sheet metal remaining. The equation
7.6x - 3.7x = 70.2 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

$18 per square foot

Explanation:

All you need to do is solve the equations since he has $70.20 of metal to use still. 7.6-3.7 = 3.9. Now we have 3.9x = 70.2; divide both sides by 3.9 to get x = 18, indicating that each square foot of sheet metal costs $18
