Each distribution center needs to receive 10 shipments per month. The distance from each plant to the respective distributing centers is given below: Distance (miles) Distribution Center 1 2 3 4 1 800 1300 400 700 (Plant) 2 1,100 1,400 600 1,000 3 600 1200 800 900 The freight cost for each shipment is $100 plus 50 cents per mile. How much should ne shipped from each plant to each of the distribution centers to minimize the total shipping costs?
