Tatiana manages a store that sells MP3 players. Each Master Blaster takes 3 hours to create the plastic pieces, 2 hours to create the electronics, and 20 hours of labor to assemble the final product. Each Rocker requires 1 hours to create the plastic pieces, 6 hours to create the electronics, and 11 hours of labor to assemble the final product. The factory has 270 hours to create the plastic pieces, 750 hours to create the electronics, and 1865 hours of labor to assemble the final product each week. If each Master Blaster generates $17 in profit, and each Rocker generates $14, how many of each of the MP3 players should Tatiana have the store sell each week to make the most profit
