You use an exponential decay equation. The equation for exponential decay is:
[tex]P(t) = P0(1-r)^t[/tex],
where P(t) is the population in a period of time t,
P₀ is original population (3000 in this case),
r is the rate (1.1% in this case),
t is time (5 in this case).
So now substitute the values in.
[tex]P(5) = 3000(1-0.011)^5[/tex]
P(5) = 2838.59
Directions say to round to the next whole number,
So the population in 5 years is 2838
