The population of a country is 9.7 x 107, and is increasing by 8.7 x 105 people each year. Show your work for each calculation, and answer in scientific notation: 1. How many new people are added after 25 years? 2. What is the population after 25 years?


 Given:

Population of the country = 9.7 X 10^7

Annual growth = 8.7 X 10^5

 

Population growth in 25 years = 8.7 X 10^5 X 25

= 2.175 X 10^7 (Number of people added after 25 years)

 

Population after 25 years = 9.7 X 10^7 + 2.175 X 10^7

= 11.875 X 10^7 (The population after 25 years<span>)</span>
