今天的小学数学应用题,CFC有牛人能做对吗?

but the gift (which cost him 18) is not in his possession anymore

by your logic then, it is 79 plus 18, still not making it to 118.

in my eyes, the merchant only lost 79 bucks.

亏: 176元.

1. get real 100 (+) from neighbor, return 79 (-) to buyer, keep 21 (+)
2. return real 100 (-) to neighbor, get fake 100 back (nothing)
3. loose an item worth 18 (-).

Total loss +21 -79 -100 -18 = -176

are you gay or lesbian? if not, better not use the word pride; it is misleading.
 
需要回炉的真不少。。

礼物成本是18元

用自己的真钞票换假的是100


so:100+18=118

yes, my mistake, I forgot he only gave the guy 79

so maybe should be 79+18


why no 18 in your answer? pls explain

So let us dumb folks figure it out since the smart ones and non-brave ones are not brave enough to enlighten us.

So go back to the question: 现在问题是:王老板在这次交易中到底损失了多少钱?


一天有个年轻人来到王老板的店里买了一件礼物

  这件礼物成本是18元,标价是21元。

  结果是这个年轻人掏出100元要买这件礼物。


  王老板当时没有零钱,用那100元向街坊换了100元的零钱,找给年轻人79元。


  但是街坊後来发现那100元是假钞,王老板无奈还了街坊100元。
  现在问题是:王老板在这次交易中到底损失了多少钱?

For me, the 18 bucks was lost in previous transaction; at the current transaction, 王老板 only gave out 79 bucks.
 
I support this one.

no the 18 bucks was lost because of this transaction
 
netwt2总是有言外之意。。我为什么喜欢骂他啊?
我看netwt2这个数学题做得很好啊,当然就不应该骂他了。。。

另外,我也强烈呼吁netwt2把那个女孩的头衔去掉,你们难道觉得这对那个女孩公平吗?netwt2为什么可以这样做,那个女孩喜欢,同意吗?

不过是netwt2讽刺挖苦那个女孩,netwt2一贯的做法而已。

或者netwt2自己说明白??

no the 18 bucks was lost because of this transaction

no, the 18 bucks was (were)lost last time because he got something that was worthless (i mean, could not be sold); at current transaction he only lost the 礼物.


suppose you buy one share of a company stock at $100 on September 1 05 and on September 11, 06 the company go belly up and one share is $0. Do you lose money in 05 or 06? for me, it is 05, the time money leaves me.

r u sure "he got something that was worthless (i mean, could not be sold); "???a

Put it this way, if he did not receive the counterfeit or he sold the gift to somebody else?

It is not he got something worthless. It's just because somebody cheated the valuable, just the way his 100 was cheated.

So, it can't compare with stock.
