To determine how many people would vote in a city with 25,000 people, we can use proportions.
Let's set up the proportion:
\frac{{\text{{Number of people voting}}}}{{\text{{Total number of people}}}} = \frac{{\text{{Number of voters in the survey}}}}{{\text{{Total number of voters in the survey}}}}
Plugging in the known values, we have:
\frac{{\text{{Number of people voting}}}}{{25,000}} = \frac{3}{7}
To solve for the number of people voting, we can cross-multiply:
7 \times \text{{Number of people voting}} = 3 \times 25,000
7 \times \text{{Number of people voting}} = 75,000
Dividing both sides by 7, we get:
\text{{Number of people voting}} = \frac{75,000}{7}
Simplifying, we find:
\text{{Number of people voting}} \approx 10,714.29
Rounding to the nearest whole number, we can conclude that approximately 10,714 people would vote in a city with 25,000 people.
