Answer 2

Question:-

A town has a population of 10000 and grows at 2.5% every year. What will be the population after 7 years to the nearest whole number ?

Answer:-

Given:-

`\bullet` Population
`(P_0)` = 10000

`\bullet` Rate (r) = 2.5%

`\bullet` Time (t) = 7 years

To Find:-

The population after 7 years.

Solution:-

We know the formula,

`{ \boxed{\rm \red {P_0(1 \: + \: r)^t}}}`

Now, putting the values we get,

`\bf 10000(1 \: + \: 0.025)^7`

`\bf 10000(1.025)^7`

`\bf = \: 11886.86`

The population after 7 years to the nearest whole number is 11886.86 . [Answer]
