Suppose the following optimal tableau is obtained

Suppose the following optimal tableau is obtained by solving a linear programming model with maximize objective function, where x4 and X, are the main decision variables in the linear programming model. Basic Z X1 0 1 0 X2 0 -2 -3 X3 0 0 X4 2 1 3 Right Hand Side (RHS) 2 2 3 X1 X3 By observation, justify whether this linear programming model consists of more than one optimal solutions. (3 marks) Give a case study example that applies sensitivity analysis concept. Based on the given example, discuss the objective and importance of using sensitivity analysis. (4 marks)
