Answer to Question 1

In both cases, the firm compares costs with potential revenues. As long as the wage equals the marginal revenue product of labor, the additional revenue just covers the additional costs of hiring labor and the firm is maximizing profits. By producing where price equals marginal cost, the firm is producing up to the point where additional costs equal additional revenues.

Answer to Question 2

Yes, the firm is currently maximizing profit. The firm should hire labor and capital such that MPL/PL is equal to MPK/PK. In this case, MPL/PL (2) is equal to MPK/PK (2). Thus, the firm is maximizing profit.
