"In this way, at the beginning, everyone paid 10 yuan, and now it is returned to 1 yuan, that is, 10- 1 = 9, and everyone only spent 9 yuan money."

If you don't analyze the topic like this, people who look at the topic won't think so.

It's actually very simple,

It should be analyzed as follows: 25+ in the hands of the boss, 2+ in the hands of three people, 1 yuan (add up to 3 yuan) =30 yuan.

Think about it. What would the waiter do if he gave the three men five dollars? Let's just say that the boss gave the waiter 6 yuan.

In this way, if everyone gets back 2 yuan, it means paying 24 yuan, that's right.

Furthermore, if the boss gave the waiter 8 yuan, the waiter gave everyone 2 yuan and took 2 yuan himself, then even if everyone paid 8 yuan,

In this way, everyone's 8 yuan (***24)+ 2 yuan in the waiter's hand =26 yuan.

Therefore, this is unacceptable. As long as the more money returned to passengers, the less money.

There is an inseparable number here, which is why it is so misleading.
