Best way to start this is set up your ground work...
Adult= A Student =S
A + S = 292
A3 + S1 = 470$
this will be your system of equations now set up your matrix and have A or S at the bottom stand alone.
Answer:
$39 per square foot.
Step-by-step explanation:
The cylinder has a height of 2 feet and a radius of 5 feet.
The total cost of the metal will be (assuming US dollars) $8572.20.
And we want to determine the cost per square foot.
First, we can find the surface area of the cylinder. The surface area for a cylinder is given by the formula:

Where r is the radius and h is the height.
Since the radius is 5 feet and the height is 2 feet and using 3.14 for π, the surface area is:

Therefore, to find the cost of metal per square foot, we can divide the total cost over the amount of surface area. Hence:

So, the metal costs $39 per square foot.
