doubling time for population....

Question

Find the doubling time for a city whose population is growing by 17% per year.

The doubling time is ....

Answer 1

P = P_o(1.17)^t P = Population P_o = Population at time(t) = 0

2P_o = Po(1.17)^t 2 = (1.17)^t log(2) =t*log(1.17)

t = log(2)/Log(1.17) = 4.41 years
