A student, solving an LP using the simplex

A student, solving an LP using the simplex method, has arrived at the following tableau. 23 21 0 22 0 Si 2 4 8 S2 -6 0 0 0 4 0 S3 2 4 0 | 10 4 0 8 4 0 3 12 2 14 1 3 0 -5 0 0 13 0 -14 (a) Determine the basic feasible solution that corresponds to the tableau. X1 = X2 = X3 = Sy = 52 = S3 = (6) Determine the value of the objective function z at this point. Za (c) What would you do next? Onothing - we have reached the optimal solution Onothing - the LP is unbounded Omove to a new tableau using the (1,5) entry as pivot Omove to a new tableau using the (3.5) entry as pivot Omove to a new tableau using the (1,3) entry as pivot Omove to a new tableau using either the (2,3) or the (3.3) entry as pivot
