Calculate the marginal rate of technical substitution for the Cobb-Douglas production function Q = 30K 0.1 0.6 when K = 600 units and L = 500 units. Hence estimate the increase in capital required to maintain the current level of output when labour decreases by 3.0 units. MRTS = (Round your answer to three decimal places as needed.) If labour decreases by 3.0 units then the increase in capital required to maintain current output is (Round your answer to two decimal places as needed.) units.
