A carpenter makes tables and chairs. Each table can be sold at the price of $100 and each chair at the price of $40. The carpenter works a maximum of 40 hours per week and spends 5 hours to make a table and 2 hours to make a chair. Each table needs 50 pounds of wood and 30 screws. Each chair needs 20 pounds of wood and 10 screws. Each pound of wood costs him $0.75 and 100 screws cost him $5. Customer demand requires that he makes at least twice as many chairs as tables. The carpenter stores the finished products in his garage, and there is room for a maximum of 9 furniture pieces each week. He should make at least 2 chairs each week. How many tables and chairs should he make to maximize his profit during a week?
