A studio that makes statuettes is trying to maximize its income. Their two primary products are the Venus and David statuettes. Each Venus requires 6 minutes of machine time to rough cut the shape and 12 minutes of craftsman time to finish the details. The David requires 9 minutes on the machines and 6 minutes with the craftsman's hand. The studio is limited each day to 54 minutes of machine time and 72 minutes of craftsman time. Both use 35 pounds of stone, and the studio has 245 pounds of stone available per day. If each Venus brings in a profit of fifty dollars, and each David brings in eighty-three dollars, how many statuettes of each type should the studio make each day?
