Consider the following L.P. Model: Only look at the graph in the image above

Maximize

Z=30X1+10X2

Subject to:

3X1+1X2270 (C1)

1X1+1X2160 (C2)

1X190 (C3)

1X240 (C4)

X1,X20

Constraints,C1,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).

b) Is there more than one optimal solution?
