The marginal product of the fourth worker is the additional output from hiring the fourth worker, calculated as the difference in output between four workers and three workers. With three workers, the company can mow 12 lawns, and with four workers, it can mow 14 lawns. Therefore, the marginal product of the fourth worker is 14 - 12 = 2 lawns.
