Best Brands Appliance Mart is getting ready for its annual Labor Day sale. There are two Best Brands stores, one in midtown Manhattan and another in Amityville. Merchandise is stored in two warehouses, one in Brooklyn and one in Baldwin. From experience in past years, the owners know the big mover during the sale is tablets. The Manhattan store needs 500, while the Amityville store will require 400. Each warehouse has 600 tablets in stock. It costs $1 and $2 to ship a tablet from Brooklyn to Manhattan and to Amityville, and $2 and $4 to ship one from Baldwin to Manhattan and Amityville. What is the best shipping strategy for getting the tablets from the warehouses into the stores to minimize the shipping cost?
