Assum the short run production function of afirm given by Q=kL-0.2k^2-0.1L^2.If Lis Variable Input and k is fixed 10.
The marginal product of labor (MPL) is given by MPL = dQ/dL = k - 0.2L.
At L = 10, MPL = k - 0.2(10) = 10 - 2 = 8.
Therefore, the marginal product of labor when L is 10 and k is fixed at 10 is 8.
