Final answer:
To round a number to the nearest thousand, we look at the hundreds place and follow specific rules.
Step-by-step explanation:
To round any number to the nearest thousand, we look at the hundreds place. If the number in the hundreds place is 5 or higher, we round up. If the number is 4 or lower, we round down. In this case, the number that rounds to 9,000 is 9,485. The hundreds place digit is 8 which is greater than 5, so we round up to the nearest thousand.
