##### Population Growth Logic

We model our population growth equation, P(t) using the following variables:

P_{0} as our initial population, p as our percent growth, and t as the units of time.

##### Our Population Growth Formula is:

P(t) = P_{0}(1 + p)^{t}

##### We are given the following values:

P_{0} = 100000, p = 0.07, and t = 19

Since the population increases, we add p = 0.07

##### Using our given values, our population model is:

P(t) = 100000(1 + 0.07)^{t}

P(t) = 100000(1.07)^{t}

##### The problem asks for P(19)

P(19) = 100000(1.07)^{19}

P(19) = 100000(3.6165275350338)

P(19) = **361652.75350338**

##### Round our answer:

Rounded to the nearest integer, our population is **361653**

##### What is the Answer?

Rounded to the nearest integer, our population is **361653**
