In a Linear Programming Problem Involving Two Decision Variables,a Change

question 35

Multiple Choice

In a linear programming problem involving two decision variables,a change in one of their coefficients will:

• A)always change the optimal solution since the slope of the objective function changes.
• B)typically change the feasible region till a stage,beyond which the constraint functions become nonbinding.
• C)never change the optimal solution as the other coefficient is still fixed.
• D)change the optimal solution only if the slope of the objective function's contour changes significantly.
• E)their shadow prices although the constraints are not affected directly.
