Can somebody please help me with this question.

Representation in a local community board is based on the community’s population, with 25 board members representing the first 500,000 people, and each additional board member representing an additional 30,000 people. Is the population of the town less than 500,000?

(1) There were 23 members on the community board.
(2) If the population were three times as large, the community board would have had 51 members.


Thanks
