The population of a small village has grown at an annual rate of approximately 5.5%.
How long will it take for its population of 3200 people to double at this growth rate?
:
let t = time for this to happen
1.055^t = 2
Use logs
t*log(1.055) = log(2)
use your calc
t = log%282%29%2Flog%281.055%29
t = 12.946 ~ 13 years
