Final Reduced Objective Allowable Allowable Name Value Cost Coefficient Increase Decrease Product A 1500 0 100 20 40 Product B 1000 0 300 120 60 What will happen if the objective coefficient for Product B increases to 400? Group of answer choices The problem will need to be resolved to find the new optimal solution value and shadow prices. The objective function value will change, but the values of the decision variables and the shadow prices will remain the same. The same decision variables will be positive, but their values, the objective function value, and the shadow prices will change. Nothing. The values of the decision variables, the shadow prices, and the objective function value will all remain the same.
