Question

The population of Stark county this year is 7,921 people. Last year the population was 7,547 people. Find the approximate percentage rate of growth of the county. A. 9.5% growth B. 1.05% growth C. 5% growth C. 0.95% growth

Answer 1

Option (C)

Explanation:

To determine the population we use the formula,

`P_n=P_0(1+r)^(n)`

Where
`P_n` = final population

`P_0` = Initial population

r = percentage growth

Now we substitute these values in the formula,

`7921=7547(1+r)^1`

`(7921)/(7547)=(1+r)`

r = 1.0496 - 1

r = 0.0496

r = 0.05

Therefore, percentage growth of the population of Stark county is 5%.

Option (C). will be the answer.
