1. **State the problem:** We want to find the initial investment amount $P$ that will grow to $2500$ in 5 years with a continuous compounding interest rate of 6% per year.
2. **Formula used:** The continuous compound interest formula is:
$$A = Pe^{rt}$$
where:
- $A$ is the amount after time $t$
- $P$ is the principal (initial investment)
- $r$ is the annual interest rate (as a decimal)
- $t$ is the time in years
- $e$ is Euler's number (approximately 2.71828)
3. **Plug in known values:**
$$2500 = P e^{0.06 \times 5}$$
$$2500 = P e^{0.3}$$
4. **Solve for $P$:**
$$P = \frac{2500}{e^{0.3}}$$
5. **Intermediate step showing cancellation:**
$$P = \frac{2500}{\cancel{e^{0.3}}} \times \cancel{e^{-0.3}} = 2500 e^{-0.3}$$
6. **Calculate $e^{0.3}$:**
$$e^{0.3} \approx 1.349858807576003$$
7. **Calculate $P$:**
$$P = \frac{2500}{1.349858807576003} \approx 1852.0455$$
8. **Round to nearest cent:**
$$P \approx 1852.05$$
**Final answer:**
You should invest approximately **1852.05** now to have 2500 in 5 years with continuous compounding at 6% per year.
