Find the present value of the ordinary annuity. (Round your final answer to two decimal places.)
$2000/semiannual period for 7 years at 5%/year compounded semiannually


To find the present value of an ordinary annuity, we use the formula:

\[
PV = P \times \frac{1 - (1 + r)^{-nt}}{r}
\]

Where:
- $ PV $ is the present value of the annuity.
- $ P $ is the payment amount per period.
- $ r $ is the interest rate per period.
- $ n $ is the number of periods per year.
- $ t $ is the number of years.

Given:
- $ P = 2000 $ (payment per semiannual period)
- $ r = \frac{5\%}{2} = 0.025 $ (interest rate per semiannual period)
- $ n = 2 $ (since it is compounded semiannually)
- $ t = 7 $ years

The total number of periods $ nt $ is:

\[
nt = 2 \times 7 = 14 \text{ periods}
\]

Now, substitute the values into the formula:

\[
PV = 2000 \times \frac{1 - (1 + 0.025)^{-14}}{0.025}
\]

Let's calculate this step by step:

1. Calculate $ (1 + r)^{-nt} $:

\[
(1 + 0.025)^{-14} \approx (1.025)^{-14} \approx 0.69832
\]

2. Calculate $ 1 - (1.025)^{-14} $:

\[
1 - 0.69832 = 0.30168
\]

3. Calculate the fraction:

\[
\frac{0.30168}{0.025} \approx 12.0672
\]

4. Finally, multiply by the payment amount $ P $:

\[
PV = 2000 \times 12.0672 = 24134.40
\]

So, the present value of the ordinary annuity is **$24,134.40**.
