Example 3

Range of Feasibility

Answer:

A dual price represents the improvement in the

objective function value per unit increase in the right-

hand side. A negative dual price indicates a

deterioration (negative improvement) in the

objective, which in this problem means an increase in

total cost because we're minimizing. Since the right-

hand side remains within the range of feasibility,

there is no change in the optimal solution. However,

the objective function value increases by $4.50.
