The result of the expression $100(\exp(-0.297) - 1)$ is approximately $-25.70$.

Would you like more details or have any questions?

Here are five related questions for further practice:

1. How would the result change if the exponent was positive, i.e., $\exp(0.297)$?
2. Can you calculate $100(\exp(-0.5) - 1)$?
3. How does the value of $e^{-x}$ behave as $x$ increases?
4. How would the expression change if multiplied by a factor other than 100?
5. What is the derivative of $f(x) = 100(\exp(-x) - 1)$?

Tip: The function $\exp(-x)$ is used often in decay models and approaches 0 as $x$ increases.
