Answer:
An annual increase of 3.24% of the population.
Step-by-step explanation:
The population did not increase by the same number each year, because:
First 5 years:
1000 - 1162 = 162 people
Second 5 years:
1350 - 1162 = 188 people
Third 5 years:
1568 - 1350 = 218 people
What it says is that numerically the same number of people did not increase every 5 years, but if I increase by the same percentage, to calculate this percentage we divide the new people by the number that there were originally, that is to say:
First 5 years:
162/1000 = 0.162 = 16.2%
Second 5 years:
188/1162 = 0.1618 = 16.2%
Third 5 years:
218/1350 = 0.1615 = 16.2%
Which means that per year I increase by:
16.2 / 5 = 3.24%
