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 count class=

Answer :

Answer:

Option (C)

Step-by-step explanation:

To determine the population we use the formula,

[tex]P_n=P_0(1+r)^{n}[/tex]

Where [tex]P_n[/tex] = final population

[tex]P_0[/tex] = Initial population

r = percentage growth

Now we substitute these values in the formula,

[tex]7921=7547(1+r)^1[/tex]

[tex]\frac{7921}{7547}=(1+r)[/tex]

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.
