Emmanuel manages a company that makes and sells two kinds of microphones, the Thumper and the Rocker. Each Thumper takes 9 hours to create the plastic parts, 4 hours to create the electronics, and 2 hours for assembly. Each Rocker requires 2 hours to create the plastic parts, 9 hours to create the electronics, and 4 hours for assembly. The factory can handle a maximum of 3960 hours to create the plastic parts, 2367 hours to create the electronics, and 1104 hours for assembly each week. If each Thumper generates $7 in profit, and each Rocker generates $5, how many of each of the microphones should Emmanuel have the company make and sell each week to earn the most profit
