8. Assume that the reduced cost of a decision variable is -$20 for a maximization problem. This implies that the objective function value will decrease by $20 if we do not produce any units of this product the objective function value will not change if we produce an additional unit of this product the objective function value will increase by $20 if we produce an additional unit of this product the shadow price value will decrease by $20 if we produce an additional unit of this product the objective function value will decrease by $20 if we produce an additional unit of this product SEE GLOSSARY. era-99's
