The Stamper company make two varieties of stapler. Model H is of high quality and they make a profit of $1 per stapler sold with a market size of 2500 per week while Model S is of medium quality and they make a $0.6 per stapler sold with a market size of 5000 per week. The factory uses the same equipment to make the two models. If only S staplers were made, then the stamping section could handle 5000 per week, the assembly section 6000 per week and the paint section 8000 per week. The H staplers take 25 % more stamping time, 50% more assembly time and 150% more printing time than S staplers. At least 25% of the staplers made must be Model S.
