(12 points) If the price of labor is w = 48, and the price of capital is r = 12, how much labor and capital should the firm hire in order to minimize the cost of production if the firm wants to produce output Q = 10?

Respuesta :

Answer:

l=9, k = 36

Explanation:

Let a firm's production function= Q = L1/2*K1/2.

Price of labor is given as, w = 48

Price of capital is given as, r = 12

Formula for Cost, c = w*l + 12*k

When we put the value of Q as 10 om the first equation, we get

18 =  L1/2*K1/2

Thus, k = 324/l which is out first equation.

c= 48*l + 12*k where we place the value of k we got from first equation.

c = 48*l +12*(324/l)

After calculation of above equation, we will get l = 9

k (from first equation)= 324/9 = 36
