Final answer:
To find the optimal product mix and the dual price of the raw material for the company, one must consider the sales volume of product A and the raw material constraints. For the exercise regarding Doggies Paradise Inc., we calculate total revenue, marginal revenue, total cost, and marginal cost for different output levels and identify the profit maximizing quantity where marginal cost equals marginal revenue.
Step-by-step explanation:
To determine the optimal product mix for the company manufacturing products A, B, and C, we must consider several constraints. The sales volume of product A should be at least 50% of the total sales, and the maximum units of A sold per day cannot exceed 75 units. Additionally, there's a constraint on the raw materials, with a maximum daily availability of 240lb. The raw material usage rates are 2lb, 4lb, and 3lb per unit for products A, B, and C respectively. With unit prices at $20, $50, and $35 for A, B, and C, the objective is to maximize revenue.
To solve part b), determining the dual price of the raw material resource, we would usually rely on linear programming methods such as the simplex algorithm to find the shadow prices or dual values. As the availability of the raw material increases by 120lb, the optimal solution and the change in total revenue can be recalculated using the dual price derived from the original problem.
For part c), the change in the maximum demand for product A by ±10 units, we would adjust the constraints for product A's production and recalculate the optimal mix, using the dual price to assess the impact on total revenue due to this change in constraint.
Profit Maximizing Quantity for Doggies Paradise Inc.
Considering the information given for Doggies Paradise Inc., we can compute the total revenue, marginal revenue, total cost, and marginal cost for each output level. By plotting the total revenue and total cost curves on one diagram, and the marginal revenue and marginal cost curves on another, we can identify the profit maximizing quantity where marginal cost equals marginal revenue.
