Consider the simplex tableaux for the Wyndor Glass Co. problem given in Table 4.8. For each tableau, give the economic interpretation of the following items:
(a) Each of the coefficients of the slack variables (x3, x4, x5) in row 0
(b) Each of the coefficients of the decision variables (x1, x2) in row 0
(c) The resulting choice for the entering basic variable (or the decision to stop after the final tableau)
