1. Consider the following production function: Q = f(K, L) = (K^1/2) (L^1/2)

a) Place capital on the vertical axis and labor on the horizontal axis. Determine the marginal rate of technical substitution.

b) Suppose that the price of capital is $10, 000, and the price of labor is $10, 000. What is the ratio of capital to labor that allows the firm to produce any given quantity of output as cheaply as possible.

c) Suppose that the price of capital increases to $30, 000. What is the ratio of capital to labor that allows the firm to produce any given quantity of output as cheaply as possible.

d) The price of capital is $10, 000, and the price of labor is $10, 000. Given this production technology determine the cost of producing 100 units of output, the average cost of producing 100 units, the capital to labor ratio, the factor demand for capital and the factor demand for labor.  

e)Suppose the price of capital increases to $40, 000. Determine the minimum cost of producing 100 units of output. What happens to the factor demands for capital and labor? If the factor demands change, explain why they change.
