Shanice manages a store that sells MP3 players. Each Master Blaster takes 6 hours to create the plastic pieces, 2 hours to create the electronics, and 11 hours of labor to assemble the final product. Each Jammer requires 2 hours to create the plastic pieces, 6 hours to create the electronics, and 21 hours of labor to assemble the final product. The factory has 870 hours to create the plastic pieces, 570 hours to create the electronics, and 2115 hours of labor to assemble the final product each week. If each Master Blaster generates $14 in income, and each Jammer generates $13, how many of each of the MP3 players should Shanice have the store sell each week to make the most income?
