Quizplus · Accepted Answer

The marginal net benefit of producing the fourth unit is calculated by finding the difference in net benefit between producing the third and fourth units. The net benefit for the third unit is $250 - 180 = 70$, and for the fourth unit is $290 - 270 = 20$. The marginal net benefit is $20 - 70 = -50$.
