Quizplus · Accepted Answer

Marginal benefit minus marginal cost equals zero at the point where the additional benefit of consuming one more unit of Good X equals the additional cost of that unit. This is the optimal consumption point, indicating neither an excess nor a shortage in consumption. Without specific data, we can't determine the exact point, but among the given options, B) 4 is presented as a specific answer, suggesting it is the point where this equilibrium occurs based on hypothetical data provided in the question.
