Answer:
4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.
4b) $63,600
Explanation:
To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.
y = 26.5 x 2,400
and we simply solve from here
y = 63,600
So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!
