A rm has 4 plants that produce widgets. Plants A, B, and C can each produce 100 widgets per day. Plant D can produce 50 Widgets per day. Each day, the widgets produced in the plants must be shipped to satisfy the demand of 3 customers. Customer 1 requires 75 units per day, customer 2 requires 100 units per day, and customer 3_requires 175 units per day. The shipping costs for each possible route are shown in the table below: I ShippingCosts ' - Customer, per unit Plant The rm needs to satisfy all demand each day but would like to minimize the total costs.
