ail store stocks two types of shirts A and B. These are packed in attractive cardboard boxes. During a week the store can sell a maximum of 400 shirts of type A and a maximum of 300 shirts of type B. The storage capacity, however, is limited to a maximum of 600 of both types combined. Type A shirt fetches a profit of $20.00 per unit and type B a profit of $50.00 per unit. How many of each type the store should stock per week to maximize the total profit? Formulate a mathematical model of the problem.
