Urgent!! Help me write a Five Dollars and Happiness !!

Congratulations on having a good mood, and thank you for giving me a good mood, because this post is the most comfortable post I have seen today, many posts ask questions that make people very helpless, making people feel that they don't want to help, they really can't help, because from the description of the questions, we know that the questioner does not have the ability to effectively use others to help, hey.

I play scratch music.

Scrape out a 20's.

Haha a little bigger than yours.

Ah, give me some good luck Recently, I have been unlucky enough to say ......

27 is the total amount of money spent by three people, which is 25 yuan for the boss + 2 yuan for the waiter, so in the end, 27 should not be +2 should + 3 yuan for them, 27 + 3 = 30.

I thought about it for a while, and let me explain it to you, defining negative spending and positive income. Under this definition, it is clear that the process of the question is clear, but first it must be clear that income + expenditure is = 0 in the end.

Start Guest -30 Boss +30 Waiter 0 Return 5 Yuan Guest -27 Boss +25 Waiter +2 In this title, "39 equals 27 yuan plus the waiter, the 2 yuan equals 29 yuan" This sentence is not true, if the waiter's 2 yuan is incorporated into the guest's money, this process should be 2+(-27)=-25, and then verify -25+25=0, so that it is 0 and.

I don't know if you figured it out?

How could it be possible to add two pieces to the waiter! 30 yuan for three people, 25 yuan for the boss, 2 yuan for the waiter, 3 yuan for you, 27 yuan is the money for the boss and waiter. That piece was eaten by pigs.

You're stupid 13! Why do you have to count it like this? What are you trying to prove?

Then you have to find a way to find another happy job from your leisure time.

The 9 yuan spent per person has included the 2 yuan hidden by the waiter (i.e. ***25 yuan + 2 yuan hidden by the waiter = 27 yuan = 3 * 9 yuan), therefore, when calculating the composition of the 30 yuan, the 2 yuan hidden by the waiter cannot be counted, but the 1 yuan returned to each person should be added. That is: 3 * 9 + 3 * 1 = 30 yuan is just right!

You can also think about it from another angle. The three people paid a total of 30 yuan, spent 25 yuan, and the waiter hid 2 yuan, so each person spent 9 yuan, plus the 1 yuan they shared, it was exactly 30 yuan. So the dollar was found.

Nonsense, you think, if you are anti-five yuan, there is only 25 yuan left, and in the end, 3 yuan is 28 yuan.

Boss: 25 people: 3 junior two: 2 (the last left.)

It's not equivalent to 9 yuan per person, and Xiao Erzang's is also equivalent to what they pay.
