Population Growth Logic

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

P0 as our initial population, p as our percent growth, and t as the units of time.

Our Population Growth Formula is:

P(t) = P0(1 + p)t

We are given the following values:

P0 = 12000, p = 0.05, and t = 12

Since the population increases, we add p = 0.05

Using our given values, our population model is:

P(t) = 12000(1 + 0.05)t

P(t) = 12000(1.05)t

The problem asks for P(12)

P(12) = 12000(1.05)12

P(12) = 12000(1.7958563260221)

P(12) = 21550.275912266

Round our answer:

Rounded to the nearest integer, our population is 21550





What is the Answer?
Rounded to the nearest integer, our population is 21550
