Question:

a) Solve problem 8 graphically. List all extreme points (x1, x2, z) and indicate the optimum solution. Identify the amount of unused resources (slack) for each of the extreme points.

b) What would be the effect on the optimal solution if the production time on line 1 was reduced to 40 hours? Don't just spout the solution listed in the back of your book. Indicate what causes this solution to be so.

c) What would be the effect on the optimal solution if the profit for product B was increased from $7 to $15? How about from $7 to $20?
