Question

in 1997 the population of a small town was 900. If the annual rate of increase is about 0.6% which value below expresses the population five years later?

Answer 1

`927`

Explanation:

`900 * (1+0.6\%)^5`

`900 * (1+0.6/100)^5`

`900 * (1+0.006)^5`

`900 * (1.006)^5`

`900* \:1.03036`

`927.32594`

Answer 2

927

Explanation:

Total Population = 900

Annual rate of increase = 0.6 % of 900

=>
`(0.6)/(100)* 900`

=> 0.6 * 9

=> 5.4

Rate of increase in 5 years = 5 * 5.4

= 27

Population after five years = 900+27

=> 927
