I need help with this question with an explanation.

. Work Item: - In the United States, the capital share of GDP is about 30 percent, the average growth in output is about 3 percent per year, the depreciation rate is about 4 percent per year, and the ca pitaloutput ratio is about 2.5. Suppose that the production function is CobbDouglas and that the United States has been in a steady state. (For a discussion of the CobbDouglas production function, see Claim.) a. What must the saving rate be in the initial steady state? [Hint Use the steady state relationship, 3y = (6 + n + g) k.] b. What is the marginal product of capital in the initial steady state? c. Suppose that public policy alters the saving rate so that the economy reaches the Golden Rule level of capital. What will the marginal product of capital be at the Golden Rule steady state? Compare the marginal product at the Golden Rule steady state to the marginal product in the initial steady state. Explain. d. What will the capitaloutput ratio be at the Golden Rule steady state? (Hint: For the CobbDouglas production function, the capitaloutput ratio is related to the marginal product of capital.) e. What must the saving rate be to reach the Golden Rule steady state
