2. The tableau is not optimal for either maximization or a minimization problem. Thus, when a nonbasic variable enters the solution it can either increase or decrease \( Z \) or leave it unchanged, depending on the parameters of the entering nonbasic variable. (a)Categorize the variables as basic and nonbasic and provide the current values of all the variables. \( \mathrm{AP}[8] \) 2 (b)Assuming that the problem is of the maximization type, identify the nonbasic variables that have the potential to improve the value of \( Z \). If each such variable enters the basic solution, determine the associated leaving variable, if any, and the associated change in \( Z \). \( \mathrm{AN}[11] \) (c)Repeat part (b) assuming that the problem is of the minimization type. AN [4] (d)Which nonbasic variable(s) will not cause a change in the value of \( Z \) when selected to enter the solution? AP [2] TOTAL : [25 MARKS]
