(d) The computer solution for the linear program in part (a) provides the following objective coefficient range information. Variable Objective Coefficient Allowable Increase Allowable Decrease X 8.00000 4.00000 4.00000 Y 12.00000 12.00000 4.00000 How would this objective coefficient range information help you answer parts (6) and (c) prior to re-solving the problem? The objective coefficient range for variable X is 12 x . Since the change in part (b) is within X Since the change in part (c) is outside this range, we know the optimal solution will x to 6 this range, we know the optimal solution will not change. ) change. The objective coefficient range for variable Y is 8 to 6
