Both production lines can produce all the different types of nozzles. The bronze machines needed for the bronze sprinklers require two operators and can produce up to 12.000 sprinklers. The plastic injection molding machine needed for the plastic sprinklers requires four operators and can produce up to 200.000 sprinklers. Three bronze machines and only one injection molding machine are available. What are the capacity requirements for the next four years? (Assume that there is no learning.)
