1. At the beginning, a project is expected to give you 23,000 yuan (including materials and working hours). ), the rest of the money is yours and your friends' after deducting the cost of materials and working hours from 23,000 yuan.

2. The boss initially took 16000 as the project payment, and the remaining 23000- 16000=7000 will be paid after you finish the project.

You will spend 12000 yuan to complete the project, of which 9000 yuan will come from the project payment advanced by the boss and 3000 yuan will be advanced by you and others.

4. After that, your friend spent 7000 yuan on the project, excluding the material cost.

16000 (construction funds) -9000 (engineering materials fees in construction funds, etc. ) =7000 (the part spent by friends)

The boss hasn't paid you the previous 23000- 16000=7000.

If that's the case, then: in the case of only you and your friend, you get 8500 (including personal expenses), and your friend gets 5500. Unfortunately, he has already spent 7000, so he should still owe you 1500, as follows.

1. First, the public cost of 9000 should be deducted from the total project 23000, leaving 14000.

2. You won't pay 3000 yuan in advance, leaving 1 1000 yuan.

3. Divide it equally, 5500 each.

4. So you should take 8500=3000 (advance cost) +5500 (estimated income).

Friends get 5500 (estimated income), that is, friends' income

Your net income is 8500 (taking money) -3000 (personal advance expenses) =5500, which is the same as your friend's net income.

But your friend has already spent 7000 yuan. ...................................................................................................................................................................
