The value of the objective function becomes (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 8.00000 4.00000 4.00000 Y 12.00000 12.00000 4.00000 How would this objective coefficient range information help you answer parts (b) and (c) prior to re-solving the problem? The objective coefficient range for variable X is to ---Select--- V change. The objective coefficient range for variable Y is optimal solution ---Select--- V change. Since the change in part (b) is ---Select--- v this range, we know the optimal solution to . Since the change in part (C) is ---Select--- v this range, we know the
