If the population of a country increases at a rate of 1.5% annually, and its current population is 430,000, how many years will
Alchen [17]
For this case we have an equation of the form:
 y = A * (b) ^ t

 Where,
 A: initial amount
 b: growth rate
 t: time in years.
 Substituting values we have:
 y = 430000 * (1,015) ^ t

 By the time the population is triple we have:
 3 * 430000 = 430000 * (1,015) ^ t

 Rewriting we have:
 3 = (1,015) ^ t

 Clearing t we have:
 t = log1.015 (3)

t = 73.78876233

t = 73 years
 Answer:
 
It will take for the population to triple about:
 
t = 73 years
