What does the shadow price of a resource constraint represent in a linear programming model?
Correct answer: B. The change in the optimal objective value from one extra resource unit
- A. The original cost of the resource
- B. The change in the optimal objective value from one extra resource unit
- C. The total unused amount of the resource
- D. The number of variables in the model
Explanation
A shadow price measures the marginal change in the optimal objective value caused by increasing the right-hand side by one unit, within the valid range. It is not the purchase price or the unused quantity of the resource.
