A firm's are costs that increase as quantity produced increases. These costs often show by increasing at an increasing rate. fixed costs; technological changes variable costs; constant returns to scale fixed costs; opportunity costs variable costs; diminishing marginal returns A firm's are costs that are incurred even if there is no output. In the short run, these costs as production increases. variable costs; do not change fixed costs; increase fixed costs; do not change variable costs; increase

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.)
