A grаph is shоwn with hоurly wаge in dоllаrs on the vertical axis and number of workers per day on the horizontal axis. The axes are labeled from 0 to 60 in increments of 5 with vertical and horizontal reference lines drawn to form a grid. Two lines are plotted from the origin increasing linearly to the right, with the upper line labeled marginal factor cost and the lower line labeled supply of labor. A third line labeled marginal revenue product is plotted starting in the upper left at 5 workers and 55 dollars and decreasing to the right, intersecting the marginal factor cost line at 20 workers and 40 dollars and then intersecting the supply of labor line at 30 workers and 30 dollars. The graph above shows a monopsony labor market. In the absence of any regulations, which of the following represents the number of workers the firm will hire and the wage rate it will offer to those workers?
