Answer:
9,000
Step-by-step explanation:
You would add it together.
6107 + 2960 = 9,067
You round the thousand (9) to the 0.
The rule is that if any number next to the one your rounding is higher then 5 or is 5 then the rounding number will go up, if its 4 or below if won't go up but stay the same.
9,067 would not go up but stay the same because of the rule.
Estimations are guesses from the mind so an exact answer wouldn't work but its whatever.
