A producer of pleasure boats wants to maximize revenue during the next month. Two types of boats are sold, x1 and x2. Type x1 sells for $40,000 and type x2 sells for $30,000. The x1 boats require 10 weeks of labor and 600 board feet of lumber each. The x2 boats need 3 weeks of labor and 1,000 board feet of lumber.
