The size of a rat population at the bay area of a certain city grows at a rate of `9`% monthly. If there are `240` rats currently, find how many rats (rounded to the nearest whole) should be expected in `18` months. Use `P(t) = 240(2.7)^(0.09 t)`, and let `t` be `18` months.

Remember, since the rate and time are both in months, you do NOT need to convert `t` to another unit (i.e. years)

`P(t) = ` rats.
