To solve this problem, we will use the future value formula for compound interest:

\[
A = P \left(1 + \frac{r}{n}\right)^{nt}
\]

where:
- $ A $ is the future value of the investment.
- $ P = 24000 $ is the principal (initial amount invested).
- $ r = 0.05 $ is the annual interest rate (5%).
- $ t = 18 $ is the time in years.
- $ n $ is the number of times interest is compounded per year (annually, quarterly, monthly, daily, or continuously).

### Part (a): Compounded Annually
For annual compounding:
- $ n = 1 $.

So, substituting into the formula:
\[
A = 24000 \left(1 + \frac{0.05}{1}\right)^{1 \times 18}
\]
\[
A = 24000 \times (1.05)^{18}
\]

Let’s calculate this value.

1. $ (1.05)^{18} \approx 2.4066 $.
2. Then, $ A \approx 24000 \times 2.4066 $.
3. $ A \approx 57758.40 $.

### Answer for (a):
The future value when compounded annually is approximately **$57,758.40**.

Here are related questions to deepen understanding:

1. How would the future value change if the compounding period was quarterly?
2. What effect does continuous compounding have on the future value compared to other compounding frequencies?
3. How would this calculation change if the interest rate were 6% instead of 5%?
4. What would the future value be if the investment period were reduced to 10 years?
5. Why does compounding more frequently increase the future value?

**Tip:** Compounding more frequently increases the future value because interest is added more often, allowing the investment to grow faster.

Suppose $24,000 is invested at an annual rate of 5% for 18 years. Find the future value if interest is compounded annually, quarterly, monthly, daily (365 days), and continuously.

Calculate the future value of a $24,000 investment at an annual rate of 5% over 18 years with different compounding frequencies: annually, quarterly, monthly, daily, and continuously. Explore the impact of compounding frequency on exponential growth.
