短期的盈亏平衡点怎么判断

NO.PZ2018062003000046 问题如下 In a perfectly competitive market, the firm's short-term operating breakeven point is: A.where average totcost is equto its prilevel. B.where marginrevenue curve intersects with its margincost curve. C.where marginrevenue curve intersects with its average variable costs. A is correct.In a perfectly competitive market, pri= marginrevenue = average totcost when the firm's operating is breakeven in the short term.考点盈亏平衡点解析盈亏平衡点下边际收益=平均总成本。在完全竞争的市场条件下，边际收益=商品价格所以可得，价格=平均总成本，A正确。B是利润最大化的条件C是打酱油的。 A不应该是AVC嘛？为什么是ATC？
