To find the present value $ PV $ of the investment, we use the formula for the present value of a future amount:

\[
PV = \frac{FV}{(1 + r)^{t}}
\]

Where:
- $ FV $ is the future value (given as $3,000),
- $ r $ is the annual interest rate (5%, or 0.05 as a decimal),
- $ t $ is the time in years.

Given that the investment is worth $3,000 after 7 months, we need to convert 7 months into years. Since there are 12 months in a year:

\[
t = \frac{7}{12} \approx 0.5833 \text{ years}.
\]

Now, plug the values into the formula:

\[
PV = \frac{3000}{(1 + 0.05)^{0.5833}}.
\]

First, calculate the denominator:

\[
1 + 0.05 = 1.05,
\]
\[
1.05^{0.5833} \approx 1.0285.
\]

Now, calculate the present value:

\[
PV = \frac{3000}{1.0285} \approx 2917.28.
\]

Thus, the present value $ PV $ is approximately **$2,917.28**.
