Acountry's current population is 100 million with an annual growth rate of 3.5%. if the growth rate remains constant, what will be the population in 40 years?

395,925,972 or 396 million

Step-by-step explanation:

Since the population growth rate is 3.5 annual that implies that the increase in population has to be recalculated at the end of each year (i.e. it is not a constant amount like a 100 people or a 1000 people but it changes every year)

To solve this problem we will use the following equation

Where

is population at year 't'

is initial population  i.e. 100 million

is growth rate is a fraction i.e. 3.5/100

is years passed i.e. 40

Now all we have to do is plugin the values

The answer is 395,925,972
