(a) Suppose the LP problem was a minimization problem, give the range of values of the unknown parameters, that would make the optimal cost be negative infinite (b) Suppose the problem was a maximization problem, give the range of values of the unknown parameters, that would make the current solution to be optimal. Hence state the optimal solution. (c) Suppose that it is a maximization problem and that U= -10, U-G= 0.5,explain why the current solution is feasible but not optimal. Hence proceed and determine the optimal solution.
