Explanation:

Identify the number and rounding place

The given population is \(2,998,329\). We need to round this number to the nearest ten thousand.

Locate the ten thousands digit and the deciding digit

The digit in the ten thousands place is \(9\) (from \(2,\underline{9}98,329\)).
The digit to its immediate right (thousands place) is \(8\) (from \(2,9\underline{8},329\)).

Apply rounding rules

Since the deciding digit is \(8\), which is \(5\) or greater, we round up:

• Add \(1\) to the ten thousands place: \(9 + 1 = 10\) (this carries over to the hundred thousands place, and subsequently to the millions place).
• \(2,990,000 + 10,000 = 3,000,000\).
• Replace all digits to the right of the ten thousands place with zeros.
• The rounded value is \(3,000,000\).

Answer:

• A 2,990,000
• B 2,998,000
• C 3,000,000 (Correct answer)
• D 3,008,000
