Answer:

B. Springfield has a population of 5,549 people i. 2017.

Step-by-step explanation:

We have the following function:

[tex]P(t) = 5000(1.015)^{t}[/tex]

What each of these things mean?

P(t) is Springfield's population is t years after 2010.

5000 is the population after 2010.

1.015 - 1 = 0.015 is the growth rate.

t is the number of years after 2010.

P(7)

This is the population in 2010 + 7 = 2017.

So

[tex]P(7) = 5000(1.015)^{7} = 5549[/tex]

So the correct answer is:

B. Springfield has a population of 5,549 people i. 2017.
