I cannot figure out this question. Some assistance would be very helpful!

Question 7 1 pts In a production model where the production function is Y = AK1/3L2'3 the equilibrium wage rate is equal to 2, labor supply is 27 workers and the productivity parameter is equal to 3. What is the equilibrium level of capital? (Hint: Use the fact that the wage rate equals the marginal product of labor and, in addition, that the marginal product of labor is proportional to I , the average product of labor.)
