Answer:
The correct answer is 73,000.
Step-by-step explanation:
This is because, we know that the number 7 or 70,000 represents the ten-thousands in this number. Therefore, the number 2 or 2,000 represents the thousands place, which is what we are trying to round.
In order to do so, we have to look at the number <em>behind</em> it, which, in this case, is 6.
Rule: If the number is 4 or <em>less</em>, the number before it stays the same. If the number is 5 or <em>more</em>, the number before it goes up 1.
Since 6 is larger than 5, the 2 will become a 3, while the other numbers become 0s.
Therefore, the correct answer is 73,000.
Hope this helps! :)
