C. 8550
D. 8900

Answer

To find the population of the city at the end of the year 2019, we will follow these steps:

### Step 1: Identify the initial population
The initial population of the city is given as 6000.

### Step 2: Calculate the total number of births
In 2019, there were 2050 new births in the city.

### Step 3: Calculate the total number of deaths
In 2019, there were 650 deaths in the city.

### Step 4: Calculate the number of people who migrated into the city
In 2019, 1325 people migrated into the city.

### Step 5: Calculate the number of people who left the city
In 2019, 175 people left the city.

### Step 6: Calculate the total increase in population
To find the total increase in population, we will add the number of births and the number of immigrants:
- Total increase = Births + Immigrants
- Total increase = 2050 + 1325 = 3375

### Step 7: Calculate the total decrease in population
To find the total decrease in population, we will add the number of deaths and the number of emigrants:
- Total decrease = Deaths + Emigrants
- Total decrease = 650 + 175 = 825

### Step 8: Calculate the net change in population
Now, we will find the net change in population by subtracting the total decrease from the total increase:
- Net change = Total increase - Total decrease
- Net change = 3375 - 825 = 2550

### Step 9: Calculate the final population
To find the final population at the end of 2019, we will add the net change to the initial population:
- Final population = Initial population + Net change
- Final population = 6000 + 2550 = 8550

### Conclusion
The population of the city at the end of the year 2019 is **8550**.
