Why? 2 A suggestion is made to increase the Production Level at the additional cost of $50/unit. Is this advisable? Why? 3 If the Advertising Budget is increased from the present $5000 hours to $5500, how will this increase impact the optimum profit contribution? 4 What would happen if the objective function coefficient associated with Number of Units Produced Direct Mail (D) increases up to $100 per unit? 5 For what range of profit contributions for the Number of Units Produced Business (B) will the original solution remain optimal? 6 What happens to the optimum profit contribution if the objective function coefficient associated with Number of Units Produced Business (B) drops to $80 per unit B
