2. DeMont Chemical Company manufactures fertilizer in three plants, referred to as P1, P2, and P3. The company ships its products from plants to two central DCs, designated D1 and D2, and then from the DCs to five regional warehouses, W1-W5. At the DCs, no demand occurs and no capacity limits exist. Demand is associated with the warehouses, and capacities exist at the plants. The system is described in the following two tables, one for each stage. The units for capacity and demand are pounds of fertilizer, and the unit costs are given per pound. (To) DC (From) plant P1 P2 P3 D1 D2 $1.36 $1.28 1.28 1.35 1.68 1.55 (To) warehouse (From) DC WI W2 W3 W4 W5 D1 $0.60 $0.36 $0.32 50.44 $0.72 D2 $0.80 $0.56 $0.42 $0.40 50.55 Requirement 1250 1000 1600 1750 1500 What is the minimum transportation cost of the network?
