The binding constraints for this problem are the first and second. Min. A + 2B s.t. A + B >= 300 2A + 5B <= 750 2A + B >= 400 A, B >= 0 * Denote, coefficient for B is c2, and coefficient for A is c1. 1) Keeping c2 fixed at 2, over what range can c1 vary before there is a change in the optimal solution point? 2) Keeping c1 fixed at 1, over what range can c2 vary before there is a change in the optimal solution point? 3) If the objective function becomes Min 1.5A + 2B, whatwill be the optimal values of A, B and the objective function?
