Question

1. Willie the Wave manufactures surfboards at plants in Los Angeles, San Diego and San Francisco. Willie needs to ship surfboards to Wal Mart Distribution Centers in Pittsburgh, Atlanta and Chicago. Also, the Wave wants to minimize the cost of shipping (less distance = lower cost) the surfboards from his plants to his customers. The data for the problem is summarized in the following table.
   

	Distance (in miles) From Plants to Customers
Plant	Pittsburgh	Atlanta	Chicago	Supply (Surfboards)
Los Angeles	2,400	2,100	2,000	30
San Diego	2,300	2,000	1,900	40
San Francisco	2,600	2,500	2,100	50
Demand (Surfboards)	40	60	20

What is minimum distance that Willie can achieve to ship his surfboards considering the supply and demand?
