3.2-3. (b) Maximize Z - 9,000x; +9,000 x2, subject to 4.2-1. Reconsider the model in Prob. 4.1-4. (See the model for Prob.3.2-3 given in Partial Answers to Selected Problems in the back of the book.) (a) Introduce slack variables in order to write the functional constraints in augmented form. (b) For each CPF solution, identify the corresponding BF solution by calculating the values of the slack variables. For each BF solution, use the values of the variables to identify the non- basic variables and the basic variables. () For each BF solution, demonstrate (by plugging in the solution) that after the nonbasic variables are set equal to zero, this BF solution also is the simultaneous solution of the system of equations obtained in part (a). 1 10.Xh, X., s 12.00 400 + SS 000 and 20 20
