A a population shrinks from its initial level of 27,000 at a continuous decay rate of 6.9% per year.

Question

By what percent does the population shrink each year?

Answer 1

P(t) = 27000e^-0.065t = 27000·(e^-0.069)^t = 27000·0.9333^t

^{So, each year population decreasing by 100% - 93.33% = 6.667%}
