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 it take for the population to triple?

73 years

Step-by-step explanation:

Here we have an exponential function P(t) which represents the population at time t and is given by:

where is the time in years,

is the initial amount; and

is the growth rate.

Finding the number of years it will take to triple the population by substituting the given values in the above formula to get:

Taking log on both sides to get:

Therefore, it will take 73 years for the population to triple.

answer: 298143
