Consider a perfectly competitive, profit-maximizing firm facing the following marginal product of labor function and prices:
- MPL = 0.5a(K/L)1/2
- W = 40
- R = 60
- P = 10
If total factor productivity (A) is 50 and the firm is employing 16 units of capital (K=16), how much labor (L) would the firm demand?
