Sabrina rounded the size of the park to the nearest thousands acres. Her estimate was 276,000 acres. What number could be the exact numbers of acres?

A 276,543

B 276,479

C 275,424

D 275,289

The correct answer would be ‘B’ because ...

A rounds up to 277000

B rounds to 276000

C rounds to 275000

And D rounds to 275000 as well.

Good luck with future problems m8

If the estimate is 276000, the actual number must have been rounded down if it was between 276000 and 276500 (non-inclusive), and rounded up if it was between 275500 and 276000 (inclusive). The only choice within either of these ranges is B.
