(Note that the initial simplex is not counted as an iteration. Please, clearly show your steps.) Below is the final simplex tableau: (b) (1 mark) What is the optimal solution found by the simplex method? (c) (1 mark) What is the optimal value of the problem? (d) (1 mark) How many constraints are binding? Which of them and why
