Consider the following linear programming problem:

Max Z =

$20x + $20y

Subject to:

8x + 4y 40

5x + 10y 40

x, y 0

Find the optimal profit (Z) and the values of x1 and x2 at the optimal solution.

	A	x = 5, y = 0, maximum revenue = $100
	B	x = 8, y = 0, maximum revenue = $160
	C	x = 4, y = 2, maximum revenue = $120
	D	x = 0, y = 4, maximum revenue = $80
	E	x = 0, y = 10, maximum revenue = $200
