1. **State the problem:** We need to find the population of a town after 5 years, given an initial population of 12,000 and an annual growth rate of 5%.
2. **Formula used:** The population growth can be modeled by the formula for exponential growth:
$$P = P_0 (1 + r)^t$$
where:
- $P$ is the population after $t$ years,
- $P_0$ is the initial population,
- $r$ is the growth rate (as a decimal),
- $t$ is the number of years.
3. **Apply the values:**
Initial population $P_0 = 12000$
Growth rate $r = 5\% = 0.05$
Time $t = 5$ years
So,
$$P = 12000 (1 + 0.05)^5 = 12000 (1.05)^5$$
4. **Calculate $(1.05)^5$:**
$$1.05^5 = 1.05 \times 1.05 \times 1.05 \times 1.05 \times 1.05 = 1.2762815625$$
5. **Calculate the population:**
$$P = 12000 \times 1.2762815625 = 15315.37875$$
6. **Round to the nearest whole number:**
$$P \approx 15315$$
**Final answer:** The population after 5 years will be approximately **15315** people.
