Question 547859
if 8% of the population left, this means 92% of the original population remains.  
This means that 92% is 2852.  We need to find what 100% is.  Making this a proportion question we have (where x is the original population):

{{{2852/0.92=x/1}}}
Solving for x we get 
{{{x=3100}}}



Let's double-check this:
8% of 3100 is 0.08*3100=248
If we did our question properly the amount that left plus the amount that stayed is the original
248+2852=3100 ((it worked!))

Hopefully this helps:)
