A town doubles its size every 22 years. If the population is currently 4,500, what will the population be in 88 years?

So, the population will always be 50 percent of the previous population counted.

4,500*1.50^x=y

4,500 is the population that it starts with, while 1.50 is telling that it is increasing by 50%. X is the number of years.

We are trying to find it in 88 years, so we should replace x with 4. Here is the reason, it doubles every 22 years and we are looking 88 years.

4,500*1.50^4 = 22,781.25

There can't be. 25 of a person, so the answer would be 22,781.
