Aamir's company has the production function Q=8K^0.75L^0.25, where Q measures output, K measures machine hours, and L measures labor hours. Suppose that the rental rate of capital is R=$120, the wage rate is W=$20, and the firm wants to produce 800 units of output. Use the Lagrange method to find the optimal input mix. What the optimal level of K?
Cost minimizing problem will look like
Minimize 120*K+20^L
Subject to 8K0.75L0.25=800
Lagrange will look like
First order conditions give us

Divide equation 1 by equation 2, we get
3L/K=120/20
L/K=2
L=2K
Set L=2K in equation 3, we get
800=8K0.75(2*K)0.25=8*20.25K
K=100/20.25=84.0896 (Optimal capital)
L=2K=2*84.0896=168.1792 (Optimal labor)

Tiffany's company has the production function Q=2K^0.5L^0.5,
where Q measures output, K measures machine hours, and L measures
labor hours. Let the wage rate be W, and suppose that the rental
rate of capital is R=$20 and the firm wants to produce 400 units of
output. Use the Lagrange method to find the demand curve for labor
as a function of the wage rate. Your answer will have L on the left
hand side of the equation. On the right...
A firm has a production function of Q=20K^.2*L^.8 where Q measures output, K represents machine hours, and L measures labor hours. If the rental cost of capital (r) equals $15 the wage rate (w) equals $10, and the firm wants to produce 40,000 units of output, how much labor and capital should the firm use?
A firm’s production technology is given by the production function q = 0.25 LK where L represents labor hours, K machine hours and q the amount of output. The market wage and rental rates are, w= $16 and r = $256. The firm is operating in the long run where it can adjust both inputs. (a) Suppose that the firm currently is using ten labor hours for each machine hour. Is it minimizing its long run total cost? If so...
