Future Value Ec57Ae
1. The problem is to calculate the future value (FV) of an investment using the formula:
$$FV = P \left[ \frac{(1 + \frac{r}{n})^{nt} - 1}{\frac{r}{n}} \right]$$
where:
- $P$ is the payment amount per period,
- $r$ is the annual interest rate,
- $n$ is the number of compounding periods per year,
- $t$ is the number of years.
2. Given values are $P = 100$, $r = 0.076$, $n = 12$, and $nt = 60$ (which implies $t = 5$ years).
3. Calculate the monthly interest rate:
$$\frac{r}{n} = \frac{0.076}{12} = 0.0063333...$$
4. Calculate the term inside the exponent:
$$nt = 60$$
5. Calculate the compound factor:
$$\left(1 + 0.0063333...\right)^{60} = (1.0063333...)^{60}$$
Using a calculator, this is approximately:
$$1.0063333^{60} \approx 1.42576$$
6. Substitute back into the formula:
$$FV = 100 \left[ \frac{1.42576 - 1}{0.0063333} \right] = 100 \left[ \frac{0.42576}{0.0063333} \right]$$
7. Calculate the fraction:
$$\frac{0.42576}{0.0063333} \approx 67.19$$
8. Finally, calculate the future value:
$$FV = 100 \times 67.19 = 6719$$
So, the future value of the investment is approximately 6719.
