The number of cat or dog animals required would be calculated based on the proportional representation of people to rooms in the desired city.
- Convert the total number of people (4000) to adults (assuming children do not count).
- Divide the number of rooms (2,825) by the number of people per adult (n) to find the number of animals needed.
The calculation yields approximately 400 cat or dog animals.
