​

Answer 1

i) 32100 people

ii) 674100

iii) 5%

Explanation:

The population in 2009 was : 642,000

The percent increase was by : 5%

This means the population in 2010 will be :

105/100 * 642000 = 674,100

i) Increase in population is ; 674,100 - 642,000 = 32100 people

ii) The population in 2010 was : 674,100

iii) Population of 2009 = 642000

Population of 2010 = 674,100

Increase in population = 674,100 - 642000 = 32100

Percent increase = increase/ original population * 100

Percent of increase = 32100/642000 * 100 = 5%
