Answer:
$25.44 (Final price including tax)
M=(755-800) /30-12
m= -45/18 or -2.5
y-800 = -2.5(x-12)
y-800 = -2.5x + 30
y = -2.5x + 830
y = -2.5(120) + 830
y = 530 lbs
Recall that the volume of a regular prism is given by the area of the base times the height.
Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.
Recall that the are of a triangle is given by 1/2 base times height.
Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by
