import gold jewelry wholesale 97 yuan or 100 yuan (the specific difference of these two answers is whether the profit of the gift is 3 yuan to make money, theoretically, the standard answer should be 97 yuan). In this transaction It belongs to the result of no result round -trip elements. The result of the transaction has nothing to do with the neighbors. The elements that can affect the result are only boss Wang and young people, and the money lost by Boss Wang = the money made by young people, and the neighbors did not make any money. It seems that young people use 100 yuan fake banknotes (waste paper), that is, zero cost, in exchange for gifts worth 18 yuan and 79 yuan, with a total value of 97 yuan, so Boss Wang lost 97 yuan,
The error view of individual students made the following explanation. Some people think it is 197 yuan, which is definitely wrong. First of all, only a 100 yuan counterfeit banknotes appeared. In the first trading Anything, the loss of this counterfeit banknotes was affected by his neighbor on behalf of him, and in the second transaction, his neighbor found that it was a counterfeit banknote and returned to the boss Wang. At this time In the first transaction, Boss Wang made a gift profit of 21-18 = 3, and now he has to bear the loss of 100 yuan counterfeit banknote. Then, Boss Wang lost a total of 97 yuan, which is the same as the results given by the first paragraph. Essence

first. -18 yuan. Lost 18 yuan.
Then a hundred yuan for neighbors. 118 yuan.
. Then, 79 yuan was given to young people.
Because the money is fake, no money is made. That 21-18 = 3 no longer exists. Because that money is fake.
So. 79 118 18 = 215 yuan.
If the method of addition:
When using the "Crossing Law" in the addition or subtraction, directly add or reduce from the high position from the left (at the same time whether the next bit needs to be processed and misplaced) to know the option to get the options The answer that requires accuracy is. When using the "Crossing Law" in the multiplication or division method, in order to make the results as accurate as much as possible, pay attention to the approximate direction of the intercept:
. A multiplier factor in expanding (or reduced) a multiplication factor, you need to shrink (or or Expand) another multiplication factor.
. The extension of the extension (or reduction) needs to be extended (or reduced). If you are seeking "the sum of the two pilots (that is, A*B /- C*D).
. The side of the increase (or reduced) the number of adding numbers should be reduced (or expand) On the other side.
. On one side of the subtraction of the reduction (or reduced), the other side of the reduction (or reduction) reduction.
cool jewels wholesale fashion jewelry The most important thing is the exchange of 100 yuan. From a mathematical perspective, Boss Wang gave the neighborhood when he exchanged 100 yuan, and then came back to himself. This is offset, so when calculating: cost 18 yuan 79 yuan for young people = 97 yuan. From the perspective of economics, can 100 yuan of counterfeit banknotes be changed to 100 yuan? If you can change it, it is pure SB. So Boss Wang gave the neighborhood 100 yuan. Some people said that the neighborhood gave the boss of the boss, and the boss Wang also returned the real currency, which is equivalent to no loss. The problem is that the boss Wang was replaced by fake coins, and the neighborhood gave the real money. So in the end, add 100 yuan.
to see which angle you read, both answers are right. Economically, it is equivalent to the boss's silly Liba machine to give the neighborhood 100.

In young people to buy things, replace 79 yuan with one hundred yuan of counterfeit money and 21 yuan worth of products,
and and then Boss Wang paid for 79 yuan real banknote and cost of 18 yuan, and the price of 21 yuan,
The answer came out, Boss Wang lost 100 yuan, from the perspective of maximum benefits, see the problem,
21 The things that can be sold by Yuan can be calculated by 18 yuan. These 3 yuan is also a loss.
So I think the answer should be 100 yuan

Is do n’t think of the boss's loss of 200.
The cost of things is 18, but if it is sold to others, it is worth 21, then the cost plus profit here will be lost by 21, and finding the real money 79 is the loss of cash 79. Then the neighbor 100 was lost by 100. So a total of 200 losses were lost.
