6) The following table represents an infeasible solution for a model to be solved by generalized simplex. To perform one iteration, which variable should leave x1 x2 X3 s1 s2 s3 RHS 0 -5 0 0 6 3 40 0 0 1 3 5 -2 1 0 0 -2 6 10 0 -1 1 0 -2 2 -8 a) X3 b) X1 c) S1 d) S2 hNb ola wa 7) The following table represents the optimal solution for a maximization model, where S1 is a slack variable added to the first labor time resource constraint, and S2 is a slack variable added to the second labor time resource constraint. Both resources are in hours. If the company decide to increase the availability of the second resource by 3 hours, where each hour will cost 1. Which statement is correct X1 x2 3 s1 s2 0 2 0 0 2 0 -4 RHS 80 20 10 0 1 3 1 0 0 -2 a) The company will lose, as the cost of added hours is greater than the benefit. b) Company will increase its profit to Znew = 86 c) Company will increase its profit to Znew = 83 d) The company should not buy at all as the there are unconsumed hours in the second resource
