D 5.3-5. Consider the following problem. Maximize Z= cx + cxx2 + xs. subject to X1 + 2x2 + x3 Sb 2x1 + x2 + 3x3 S 25 and X 20, X220, X3 20. Note that values have not been assigned to the coefficients in the objective function (C1, C2, C), and that the only specification for the right-hand side of the functional constraints is that the second one (2b) be twice as large as the first (b). Now suppose that your boss has inserted her best estimate of the values of c), C2, C3, and b without informing you and then has run the simplex method. You are given the resulting final simplex tableau below (where x4 and Xs are the slack variables for the respective functional constraints), but you are unable to read the value of Z Coefficient of: : Basic Variable Right Side Eq.
