An economy is characterized by the production function Y = 4*Sqrt(K*N), where K is the fixed capital stock given by K = 2500, and N is the amount of homogeneous labor units employed. The state of technology and population are assumed constant. In addition, all the classical assumptions about the labor market apply to this economy. The aggregate labor supply schedule is given by Ns = 10*(W/P) , where (W/P) is real wage.

(a) Derive the aggregate labor demand schedule, Nd , for this economy.
