这道题讲解没听懂，没说明白单位价格为什么比其他单位更低，还有第一程度垄断，为什么价格等于mc和mr，这不是完全竞争的特点吗？

这题还是有点没有听明白，麻烦老师再解释一下，谢谢

LIFO reserve is least likely to increase when inventory unit: A costs are increasing. B costs are decreasing. C levels are decreasing. 追问： 可否用这个来推？我觉得可以把自己的思路搞得更清楚一点。 LR上升，即delta LR>0.用公式：COGS(F)=GOGS(L)-detal LR来推。

LIFO reserve is least likely to increase when inventory unit: A costs are increasing. B costs are decreasing. C levels are decreasing. B 请问 当成本是上升时，只能推出LIFO REVERSE是正，并不能推出其是上升的啊？

An analyst found a reversal of $800,000 of a previous write-down of the inventories in a manufacturing company, resulting the inventory's carrying value increased to $4,000,000. Which of the following statement regarding with the inventory is most likely correct? A The company will provide explanations for this reversal in its footnotes. B The company will record a gain of $800,000 on the income statement. C The inventory has a net realizable value of $4,000,000. A IFRS required disclosures related to inventories, including the amount and explanations of any reversal of previous write-downs. The reversal will not be recorded as a gain but a reduction in COGS. $4,000,000 can be the net realizable value or the original cost of the inventory, since we are only allowed to write up to the extent of the inventory's historical cost. 请问：截图中B C选项的公式在哪里可以找到？小视频中B C 选项的推导没有太理解，可否能用公式解释一下？
