What is the impact on cost if we increase Min E requirement by 10 units? b. If the objective function coefficient of Feed B decreases by $0.15, will the optimal solution and the value of the objective function change? c. We can decrease Min A requirement by 3 units, while increasing Min B & D requirement by 1 unit. Is it worth the effort? d. If the objective function coefficient of Feed C decreases by $0.2 and the objective function coefficient of Feed E increases by $0.04, what will be the impact on cost
