1. **State the problem:**
An initial amount of 3200 is invested at an interest rate of 7% per year, compounded continuously. We need to find the amount in the account after 5 years.
2. **Formula used:**
For continuous compounding, the amount $A$ after time $t$ years is given by:
$$A = P e^{rt}$$
where:
- $P$ is the principal (initial amount),
- $r$ is the annual interest rate (as a decimal),
- $t$ is the time in years,
- $e$ is Euler's number (approximately 2.71828).
3. **Substitute the known values:**
$$P = 3200, \quad r = 0.07, \quad t = 5$$
4. **Calculate the exponent:**
$$rt = 0.07 \times 5 = 0.35$$
5. **Calculate the amount:**
$$A = 3200 \times e^{0.35}$$
6. **Evaluate $e^{0.35}$:**
$$e^{0.35} \approx 1.4190675$$
7. **Multiply to find $A$:**
$$A = 3200 \times 1.4190675 = 4540.616$$
8. **Round to the nearest cent:**
$$\boxed{4540.62}$$
So, the amount in the account after 5 years is 4540.62.
