C2 C3 and C4 have been drawn on the graph to the right. a) Using the point drawing tool, locate all the corner points for the feasible area on the graph. The optimum solution (using a corner point) is: X1 -round your response to four decimal places). X2=(round your response to two decimal places). Optimal solution value z =(round your response to two decimal places). 40- 0- 0 40 80 120 160 200 240 280 320 360 X1 b) Is there more than one optimal solution
