Based on the available information, can we find out if the optimal solution changes when we change the objective function coefficients of "Variable 2 and Variable 3 to 650 and 600 respectively? Why? (4 marks) g. Based on the available information, can we determine the optimal objective function value after the RHS of "Constraint 3" changes to 10? Why? If yes, what is the optimal objective function value after this change? (3 marks) h. Based on the available information, can we determine the optimal objective function value when we change the RHS of Constraint 1 and Constraint 2 to 4800 and 900 respectively? Why? If yes, what is the optimal objective function value after this change? (4 marks)
