Quizplus · Accepted Answer

The sensitivity range for the cost of x in a linear programming problem refers to the range within which the cost coefficient of x can vary without changing the optimal solution's basis. To determine this range, one would typically use the simplex method or sensitivity analysis post-optimization. However, without solving the linear programming problem explicitly or having the dual prices (shadow prices) for the constraints, it's not possible to accurately calculate the sensitivity range from the given information alone. The correct answer choice is provided based on the assumption that this question is theoretical and might not require detailed calculation. The sensitivity range for a coefficient in the objective function generally depends on the constraints and the current solution's optimality. Since detailed calculations or specific results from such calculations are not provided, a precise explanation based on the given data cannot be offered.
