Question

A contractor bought 8.2 ft to the second power of sheet metal. they has used 4.9ft to the second power so far and has ​$66 worth of sheet metal remaining. The equation 8.2x + 4.9x = 66 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square​ foot?

Answer 1

The sheet metal costs $5.04 per square foot.

Step-by-step explanation:

To find the cost per square foot of the sheet metal, we can start by solving the equation given: 8.2x + 4.9x = 66, where x represents the cost per square foot. Combining like terms, we get 13.1x = 66. Dividing both sides by 13.1, we find that x = 5.04. Therefore, the sheet metal costs $5.04 per square foot.
