a) I would write
P(n) = 12000(.982)^n where n is the number of years from the present
for b)
solve .25 = (.982)^n
I assume you know how to do logs.
c) have we established if you know Calculus?
That will determine how to answer that.
nope i don't, the school makes it manditory to take advanced functions before calculus
in that case I would take something like
(P(5.01) - P(5))/(5.01 - 5)
= -199
so at the 5 year point, the population is decreasing at appr 200 people/year
