A factory that makes statues is trying to maximize its income. Their two primary products are the Liberty and David statues. Each Liberty requires 36 minutes of machine time to rough cut the shape and 18 minutes of craftsman time to finish the details. The David requires 54 minutes on the machines and 12 minutes with the craftsman's hand. The factory is limited each day to 648 minutes of machine time and 216 minutes of craftsman time. Both use 14 kilograms of stone, and the factory has 196 kilograms of stone available per day. If each Liberty brings in a profit of eighty dollars, and each David brings in eighty-four dollars, how many statues of each type should the factory make each day?
