Given the following simplex tableau, complete the tableau and answer the following questions:
X1 X2 X3 S1 S2
Basis Cb | 3 4 5 0 0 |
| 1/2 1 0 1/2 -1/2 | 6
| 0 0 1 -1/4 1 | 3
Zj | |
Cj-Zj | |
a. What variables form the basis?
b. What are the current values of the decision variables?
c. What is the current value of the objective function?
d. Identify the entering column and row.
The solution completes a simplex tableau and identifies the variables that form the basis, the current values of the decision variables, the current value of the objective function and the entering column and row (see Excel file attached).
