你好，请问一下什么是economic cost和economic profit，能都有一个通俗易懂的中文解释，谢谢
NO.PZ2016010802000036 问题如下 Normprofit is best scribeas: A.zero economic profit. B.totrevenue minus all explicit costs. C.the sum of accounting profit plus economic profit. A is correct.Normprofit is the level of accounting profit suthimplicit opportunity costs are just covere thus, it is equto a level of accounting profit sutheconomic profit is zero.考点Normprofit解析正常利润就是经济利润为0时候的利润。正常利润应该等于收入减去显性成本的同时还要减去隐性成本。B不入选C就是个打酱油的，不必管它。 RT这道题AB都有道理又要回归到哪个BEST（貌似很多题目都可以用这个来强行）主观上没觉得哪个是BEST,我觉得AB都对
