Firm 1 produces output X with a cost function C_1(X)=\frac{X^2}{200}. Firm 2 produces output Y with a cost function C_2(X, Y)=\frac{Y^2}{100}-2X. Both firms face competitive markets. The competitive price of X is 6 and the competitive price of Y is \$ 5. There is no entry or exit into this market. What is the socially optimal production of X?

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.)
