What is the optimal solution and the cost represented by the objective function? b. What is the impact on cost if we increase B requirement by 10 units? c. What is the impact on cost if we decrease C requirement by 3 units? d. What is the impact on cost if we decrease C requirement by 8 units? e. It's known that we can decrease C requirement by 2 units at an additional cost of $2 per unit. What would be the impact on the objective function value? f. If the objective function coefficient of T3 increases by $50, will the optimal solution change? What about the value of the objective function
