c) The 2nd simplex tableau for the problem is given below. Use the Simplex method to generate the 3rd simplex tableau; you are only required to update the basic variable set, the Z row and the Solution column; you can leave other cells blank. From the 3rd tableau, state the plan, its profit and all resource consumption. Is the plan optimal and why?
