It would be B because rounding 9,955 would technically be 10,000 and 1,123 is basically 1,000 so 10,000-1,000 equals 9,000

Answer: The answer is (B) 9,000

Step-by-step explanation:

First, you would subtract the numbers and you should end up with.. 8,832

To show that this is correct, I will show you the step by step explanation:

1. I will subtract the numbers in the ones places of both numbers ( 5 and 3 ) that would lead me to getting 2.

2. Then, I will subtract the numbers in the tenths place, ( 5 and 2 ) and that would bring me to 3.

3. Next, I will subtract the numbers in the hundredth place, ( 9 and 1 ) that brings me down to 8.

4. Finally, I subtract the numbers in the Thousandth place, ( 9 and 1 ) and that brings me to 8 again.

So, the difference without rounding is 8,832 and the difference rounded is 9,000 because the last three numbers are above 500 all together.
