You are currently working for the supply chain management team at Baby Boom. Baby Boom manufactures and distributes two types of products: baby car seats and strollers. They operate two plants and two DCs in the United States, to serve their three main markets. They manufacture both of their products in the two plants, but there is a certain maximum capacity for each of the products in the manufacturing plants (see Table 1).

Table 1. Plant capacity (in units per month)

	Car seat	Stroller
Plant 1	1800	2000
Plant 2	1000	3500

Once the products are ready and packaged in boxes, they are sent to the DCs. DCs also have a certain maximum capacity. Since both products have a similar volume once packaged, DC capacity can be used indiscriminately by any product (see Table 2).

Table 2. DC capacity (in units per month)

	Capacity
DC1	4000
DC2	5000

From the DC, the products are distributed to the markets. The demand for each of the products in these markets is displayed in Table 3.

Table 3. Demand (in units per month)

	Car seat	Stroller
Market 1	652	1123
Market 2	1234	1523
Market 3	871	1080

Your boss has asked you to build an optimization model to determine what is the optimal transportation cost for this network. He has provided you with the distances (in miles) between plants, DCs and markets (Table 4). He also mentioned that the inbound transportation cost (from plants to DCs) is $0.0071 per unit per mile and the outbound transportation cost (from DCs to markets) is $0.0822 per unit per mile.

Table 4. Distances (in miles)

	DC1	DC2
Plant 1	78	43
Plant 2	43	14
Market 1	68	100
Market 2	11	33
Market 3	56	75

What is the optimal total transportation cost for this network?

Round your answer to the nearest integer.
