True Furniture Co., Ltd. produces desks and cabinets for computers. The production process is largely divided into woodworking and polishing. The desk requires 4 hours of woodworking and 3.5 hours of polishing, and the cabinet requires 3 hours of woodworking and 5 hours of polishing. With the currently secured manpower level, it is possible to work up to 82 hours for woodworking and 86 hours for polishing. The profit per desk is 35,000 won, and the cabinet is 28,000 won. Given the current demand, cabinet production should be less than half of desk production. True Furniture Co., Ltd. wants to determine the amount of production of desks and cabinets that can maximize total profit.
