9. A partially completed, initial simplex tableau is completed below: S: So JO X, 10 5 X 15 10 X 20 O Basis SE S: S ORO OOO 5. 0 O 0 1 6 0 300 450 100 0 0 2 0 -2 Write constraint #2 in the space below. Then copy the initial tableau on your page and complete the first iteration ONLY. 10. After you've completed the first iteration on, answer the following questions: What are the following values? X1 = X2 X3 = SI = S2 = S3 = What is the value of the objective function? Have you reached the optimal solution? Yes/No Which variable should enter the basis? Which variable should leave the basis
