The '40 years' is not part of the question. It's just there to prove that
'2% each year' has been the experience for the past 40 years, so it's
a good number to use for the rate of growth, past or future.
So, at any number of years 'Q' after the beginning of "this period",
the population was or will be
Pop = (220,000) (1.02)^Q power.
(This equation is familiar from all of the bank-interest problems
the student has done in past math classes.)
In 10 years after the beginning of "this period",
Pop = (220,000) (1.02)¹⁰ = <em>243,800 </em>(or any reasonably close number)
from 300 to 250 is well, just a change of 50 units.
if we take the 300 as the 100%, what is 50 off of it as percentage?
