3个人去HOTEL, FEE $10/person. So paid $30 total
经理决定给他们 $5 discount, , so he give waiter $5 tell him give it back to the customer.
But the waiter kept $2 for himself, so he only returned $3 dollars to the customers
So the customers each receive $1 back.
So the actually paid $9.
So the total they paid is $27
Plus waiter’s $2
Total is $29.
Where is the other dollar?
who can tell?

呵呵~~, 但是如果waiter 被警察抓住, 要他还出赃款的话, 他只有$2。总数还是不对啊。
这个例子在现实里也很常见的。
总数是25,而不是30。所以waiter的2$是减而不是加。
2楼的已经说得很清楚了。
