The Outdoor Furniture Corporation manufactures two products: benches and picnic tables, for use in yards and parks. The firm has two main resources: its carpenters (labor force) and a supply of redwood for use in the furniture. During the next production cycle, 1,200 hours of labor are available under a union agreement. The firm also has a stock of 3,500 board feet of quality redwood. Each bench that Outdoor Furniture produces requires 4 labor-hours and 10 board feet of redwood; each picnic table takes 6 labor-hours and 35 board feet of redwood. Completed benches will yield a profit of $9 each, and tables will result in a profit of $20 each. How many benches and tables should Outdoor Furniture produce in order to obtain the largest possible profit
