Packages arrive at the stockroom and are delivered on carts to offices and laboratories by student employees. The carts and packages are various sizes and shapes. The students are paid according to the carts used. There are 6 carts and the pay for their use is Product C1: $1 Product C2: $3 Product C3: $2 Product C4: $4 Product C5: $1 Product C6: $2 On a particular day, 9 packages arrive, and they can be delivered using the 6 carts as follows: C1 can be used for packages P1, P3, P4 and p7. C2 can be used for packages P2, P5, and P6, and p8. C3 can be used for packages P1, P2, P5, P6, and P7. C4 can be used for packages P3, P6, and P7 and 9. C5 can be used for packages P2, P4 and p8. C6 can be used for packages P1, P2 and P3 The stockroom manager wants the packages delivered at minimum cost.

There are three factories located at AR, IN, and TX respectively. From these locations, a certain commodity is to be delivered to each of the two warehouses situated at A and B. The revenue per commodity item is $10. The weekly demand of the warehouse A and B are respectively 50 and 35 units of the commodity while the production capacity of the factories at AR, IN, and TX are respectively 28, 22, and 35 units. The cost of transportation per unit is given as belows. Cost Warehouse A Warehouse B AR 5 3 IN 6 6 TX 2 4 To maintain a good relationship with all the factories, warehouse B requires that it receives at least 40% of its product from factory in TX. Realize that it is making good profit in warehouse A, AR requires that at least 35% of its product shipped to warehouse A. Formulate (without solving) a linear programming problem to maximize the profit.
