For all the changes in the parameters of the problem, do not start from scratch; use the methods Sensitivity Analysis. If the dual solution is asked, do not solve the dual; find the dual solution using the the optimal tableau of the primal.

1 Consider the following LP and its optimal tableau (Table 51): max z = 4x + x s.t. x + 2x = 6 - X X 3 2x + x 10 X1, X 0 a Find the dual of this LP and its optimal solution. b Find the range of values of b3 for which the current basis remains optimal. If b3 11, what would be the new optimal solution? =
