An animal reserve has 22,000 elk. The population is increasing at a rate of 12% per year how long will it take for the population to reach 88,000
Future population =FP
Present population =PP
FP = PP x [1 + R]^N
88,000 =22,000 x [1.12]^N, solve for N
4 = 1.12^N
N =Log(4) / Log(1.12)
N =12.23 Years for the population to quadruple.
