A section of the Excel output is shown below: Final Value Reduced Cost Allowable Decrease Name Objective Allowable Coefficientincrease 100 20 300 120 1500 0 40 Product A Product B 1000 0 60 What will happen if the objective coefficient for Product A decreases to 80? The objective function value will decrease by $30,000, but the optimal solution will remain the same. The problem must be recalculated because the increase caused the range of optimality to be exceeded. The problem must be recalculated because the increase caused the range of feasibility to be exceeded. The objective function value will decrease by $20, but the optimal solution will remain the same. The objective function value will decrease by $30,000 and the optimal solution will also change
