1. **State the problem:** Find the future value of an ordinary annuity with payment $650$, interest rate $1.45\%$ compounded semiannually, over 6 years.
2. **Formula for future value of an ordinary annuity:**
$$FV = PMT \times \frac{(1 + r)^n - 1}{r}$$
where:
- $PMT$ is the payment per period,
- $r$ is the interest rate per compounding period,
- $n$ is the total number of compounding periods.
3. **Calculate the interest rate per period and number of periods:**
- Annual interest rate = $1.45\% = 0.0145$
- Compounded semiannually means 2 periods per year.
- Interest rate per period: $$r = \frac{0.0145}{2} = 0.00725$$
- Number of periods: $$n = 6 \times 2 = 12$$
4. **Substitute values into the formula:**
$$FV = 650 \times \frac{(1 + 0.00725)^{12} - 1}{0.00725}$$
5. **Calculate $(1 + 0.00725)^{12}$:**
$$1.00725^{12} \approx 1.0891$$
6. **Calculate numerator:**
$$1.0891 - 1 = 0.0891$$
7. **Calculate fraction:**
$$\frac{0.0891}{0.00725} \approx 12.2966$$
8. **Calculate future value:**
$$FV = 650 \times 12.2966 = 7993.79$$
**Final answer:** The future value of the ordinary annuity is approximately **7993.79**.
