het 1 hour. 35 minutes 43 seconds * Question Completion Status The following is a L.P.P: Max Z= 5X1 + 7X2 + 6X3 (Hundreds of dollars $) s. X1 + 4X2 + 2x3 = 60 2X1 + 2X2 + 3X3 = 40 X1 + 2X2 + 2X3 =0 (production capacity; hours) (warehouse capacity; hundreds of sq. ft.) (demand for 6 oz. glasses; hundreds of cases) The optimal solution to the model as follows: Basis CB 5X1 7X2 6X3 S1 S2 S3 RHS X2 7 0 1 0.5 0 -0.5 1 10 S1 0 0 0 -1 1 1 -3 10 X, 5 1 0 1 0 1 -1 10 5 77 8.5 0 1.5 2 120 C-Z 0 0 -2.5 0 -1.5 (-2 What effect on the optimal solution (value of Z) ,if we change the profit of X3 from 6 to $1.8
