Answer:
31,000
Step-by-step explanation:
what you do is look at the number in the thousands place then you look at the number on the right of it. If the number is 5 or above the number in the thousands place goes up by one. if the number is 4 or less round down and the number in the thousands place stays the same. Every number after the number in the thousands place to the right becomes a zero no matter what.
