Not sure, I know what method they are referencing. 

However the question is taking a percentage, of Pinecrest's population to get Lakewood's population.

You can write that as:
Lakewood's population is 21 / 25 = 0.84 of Pinecrest. 

Of is usually equal to multiplication in word problems so:

$$18,000 \times 0.84 = \cdots$$

15,120

Correct. That is what Lakewood's population is, however I do not know if that is using the method they wanted.

anonymous · Answer

I think your correct.

anonymous · Answer

I am pretty sure I am, just I do not think I am using the method they wanted to be used to solve the problem. Mathematics allows multiple ways to solve one problem, so the answer would be the same regardless.
