Question

If one changes the contribution rates in the objective function of an LP problem, Select one: a. the optimal solution to the LP will no longer be optimal. b. the number of decision variables will change. c. the slope of the isoprofit or isocost line will change. d. the feasible region will change.

Answer 1

In linear programming, changing the contribution rates in the objective function may affect the optimal solution, but not the feasibility of the problem.

Step-by-step explanation:

In linear programming (LP), changing the contribution rates in the objective function will not affect the feasibility of the problem, but it will affect the optimal solution.

The optimal solution may change or remain the same depending on the specific changes made.

To determine the effect of changing contribution rates, you would need to analyze the original and new optimal solutions.

The change could result in a completely new solution or a slight adjustment to the original solution.

Therefore, option a. the optimal solution to the LP will no longer be optimal is the correct choice.
