Question 1002921: use the formula N=Ie^kt where n is the number of organisms in terms of initial population 'I' at t and k is the growth constant equal to the percent of growth per unit of time . How long will it take for the population of a certain country to double, is its annua growth rate is 8.3%. Round to the nearest year. t=_________.

Hi there,
N = I e^kt
k = 8.3% = 0.083
Make N = 2
I = 1
2 = I e^0.083t
2/1 = e^0.083t
2 = e^0.083t
ln2 = 0.083t lne (lne = 1)
t = ln2/0.083
t = 8.35 years
t = 8 years.
Hope this helps :-)
