The marginal product of labor for the fourth worker is calculated by subtracting the total product at three workers from the total product at four workers. From the table, at three workers, the total product is 70 energy drinks, and at four workers, it is 90 energy drinks. Thus, the marginal product for the fourth worker is $90 - 70 = 20$ units per period.
