2. A factory making soda employs only workers (L) and machines (K) when producing cases of soda. The factory's production function is: F (K, L) = 20 =I= min(3K, L). The price of an hour of labor is $20 (w = 20) and the price of a machine hour is $30 per hour (r = 30) a. Suppose the rm wants to produce 300 cases of soda. What will the rm's costs be? h. Suppose you notice the rm is using 25 machine hours (K) and 60 worker hours (L) the firm is no longer producing 300 units. What could you recommend to the firm in order for it to decrease costs without decreasing output? How much money would you save the firm
