Starfish Enterprises management has obtained data on the material costs for a selected job which used 300 feet of materials, while estimates for the job required only 260 feet of materials. The materials price per unit was the same. Which is not a reason for the difference in material usage? A new employee worked on the job. The material used was of poor quality. The cutting tools were in need of repair. The cost of materials increased from the time of the estimate.

1. alwaysrain irrigation, inc. would like to determine capacity requirements for the next four years. currently, two production lines are in place for making bronze and plastic sprinklers. three types of sprinklers are available in both bronze and plastic: 90-degree nozzle sprinklers, 180-degree nozzle sprinklers, and 360-degree nozzle sprinklers. management has forecast demand for the next four years as follows: 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.)
