你好，请问一下，如何理解隐形成本和显性成本的概念，强化课中没有提到，谢谢
NO.PZ2016010801000018 问题如下 Whiof the following will make economic profits 0? A.When explicit costs animplicit costs is the same amount. B.When the totrevenue is equto explicit costs. C.When the sum of explicit costs animplicit costs is equto totrevenue. C is correct.Economic profit = totrevenue – explicit cost - implicit cost.Therefore, when totrevenue is equto the sum of explicit animplicit opportunity costs, economic profit is zero.考点经济利润解析因为经济利润=总收入-显性成本-隐形成本。因此，当总收入等于显性和隐性机会成本之和时，经济利润为零。 RT
老师，把B改为，When the totrevenue is equto explicit costs animplicit cost is 0, 是不是就正确了？
何老师讲说economic cost是implicit cost, accounting cost是explicit cost，讲义上是economic profit=totrevenue-toteconomic cost,为什么这里又是economic profit=totrevenue-implicit cost-accounting cost呀？那不是应该economic profit=totrevenue - implicit cost就可以了吗？
请问，B也可以让economic profit=0，对吗？
