An online gift shop makes personalized birthday party favor kits. There are two options: Kit A or Kit B. Kit A requires 4 hours of preparation time, 1 hours of assembly time, and 1 hours of finishing time. Kit B requires 9 hours of preparation time, 1 hours of assembly time, and 0.5 hours of finishing time. There are 180 hours of preparation time, 25 hours of assembly time, and 20 hours of finishing time available each week. If each Kit A order earns a profit of $45 and each Kit B order earns a profit of $50, how many of each should be created to maximize the profit?
