To find the number of people who voted, you can calculate it as follows:
- Convert the percentage of voters to a decimal: 33% = 0.33.
- Multiply the total number of eligible voters by the decimal:
\[ \text{Number of voters} = 0.33 \times 2500 \]
\[ \text{Number of voters} = 825 \]
So, approximately 825 people voted.
The correct answer is: 825.
