For a parade, attendance was rounded as 10,000 to the nearest hundred. What was the greatest and least number of people that could have attended the parade? Explain your
answer.

(9,950 to 10,049)

Step-by-step explanation:

The nearest hundred is the third digit (counting from the right).

When we round up/down, we must look at the previous digit (the second in this case).

If the digit is larger than 5, we round up

if the digit is 5 or less, we round down.

Then if the rounded number is 10,000.

The rounded down version will be:

10,049

(49 < 50, then we should round down to 10,000)

The rounded up version will be:

9,950.

this number would be the smallest number that can be rounded up to 10,000.

Then the possible range is:

(9,950 to 10,049)
