[Blindmath] population growth equations

[Alastair Irving]

Hi

I don't think this list should be used for questions of this sort, 
unless there's an accessibility issue causing the problem.  Having said 
that, since I don't want to send a purely negative response, here's how 
you would solve your problem:

Step 1: find the rate of growth per year by solving
x^10=2
to get x approximately 1.07 (this means the population grows by about 7 
per cent each year).

Step 2: In 12 years the population will increase by a factor x^12 (which 
is about 2.3), so you multiply the original population by this.
