To round a number to the nearest hundred, we count two places to the left of the decimal point, or from the last digit if the number is a whole number.

If the second digit from the last digit is upto 5, we add 1 to the preceding digit and we complete the last two numbers with zeros.

Therefore, any number from 11,950 to 12,049, will result to 12,000 when rounded to the nearest hundred.

The * correct answer* is:

Any number greater than or equal to $11,950.

**Explanation**:

To round a number to the nearest hundred, we look at the place value behind this; this would be the tens place.

In order to round up, we need the digit in the tens placed to be 5 or greater. This will cause the hundreds place to "round up" to the next value, which would be 10; this makes the number $12,000.
