(b) If a new activity x9 with constraint coefficient and an objective coefficient 7 is added to the problem, would the optimal solution be different? (c) How small can the first constraint coefficient b1 be, without violating feasibility? (d). If we add the constraint 2x1-x2 +4x3 ≤ 2 to the model discussed, would the previous optimal solution still be optimal? If not, find a new optimal solution Below is an optimal simplex tableau of a problem with ≤ con- straints, and x6, x7, and x8 as the slack variables.
