David runs a factory that makes Blu-ray players. Each R80 takes 8 ounces of plastic and 3 ounces of metal. Each D200 requires 4 ounces of plastic and 6 ounces of metal. The factory has 368 ounces of plastic, 444 ounces of metal available, with a maximum of 20 R80 that can be built each week. If each R80 generates $17 in profit, and each D200 generates $14, how many of each of the Blu-ray players should David have the factory make each week to make the most profit?
