A section of output from Excel is shown here: Final Shadow Constraint Allowable Allowable Name Value Price R.H. Side Increase Decrease Constraint 1 75 4 80 20 30 What will happen if the right-hand-side of constraint 1 increases to 100? Question 4 options: The optimal values of the decision variables will remain the same. The optimal value of the objective function will increase by 4. The constraints will remain the same. The optimal value of the objective function will increase by 4. Uncertain, the question will need to be reformulated. The constraints will remain the same. The optimal value of the objective function will increase by 80
