6. The transportation problem in Table 5.29 gives the indicated degenerate basic solution

(i.e., at least one of the basic variables is zero). Suppose that the multipliers associated with this solution are UI = 1, Uz = -1, VI = 2, V2 = 2, and V3 = 5 and that the unit cost for all (basic and nonbasic) zero Xij variables is given by Cij = i + j(), - 00 < 8 < 00

(a) If the given solution is optimal, determine the associated optimal value of the objective function.
