It appears you are mentioning elements related to financial calculations, specifically examples of compound interest or exponential growth in finance where you might use the formula \( S = P e^{rt} \). Here's a breakdown of the terms and their meanings in the context of your notation:
- **S**: The future value of the investment/loan, including interest.
- **P**: The principal amount (the initial amount of money).
- **e**: Euler's number, approximately equal to 2.71828, which is the base of natural logarithms, used in continuous growth calculations.
- **r**: The annual interest rate (in decimal form).
- **t**: The time the money is invested or borrowed for, in years.
### Calculating Future Value with Continuous Compounding
Given your example involves a principal of **$10,000** and an interest rate, we can clarify a bit further:
1. **Principal \(P\)**: $10,000
2. **Time \(t\)**: Mentioned variously as 15 years or 645 years, which seems to be an error. Let's assume you're mostly interested in 15 years.
3. **Rate \(r\)**: Assuming "1.0875" is the interest rate, it's interpreted as 108.75%. However, this is quite high, so if it's %2.7182818, you'd possibly want to clarify it further as well.
### Example Calculation
If we take \(P = 10,000\), an interest rate \(r = 0.0875\) (8.75%), and time \(t = 15\) years, the formula would be:
\[
S = P e^{rt}
\]
Substituting in the values:
\[
S = 10,000 \times e^{0.0875 \times 15}
\]
Calculating the exponent first:
\[
0.0875 \times 15 = 1.3125
\]
Then calculating \(e^{1.3125}\):
\[
e^{1.3125} \approx 3.72
\]
Now calculating \(S\):
\[
S \approx 10,000 \times 3.72 \approx 37,200
\]
### Conclusion
Thus, if all values and parameters are correctly interpreted, after 15 years at an 8.75% interest rate compounded continuously, an investment of $10,000 would grow to approximately $37,200.
