Step 1 :We are given that the final amount (A) is $50,000, the annual interest rate (r) is 7% or 0.07 in decimal form, and the time (t) is 17 years. We need to find the initial investment (P).
Step 2 :The formula for continuous compounding is \(A = P e^{rt}\). We can rearrange this formula to solve for P: \(P = \frac{A}{e^{rt}}\).
Step 3 :Substituting the given values into the formula, we get \(P = \frac{50000}{e^{0.07 \times 17}}\).
Step 4 :Calculating the above expression, we find that \(P \approx 15211.0632033352\).
Step 5 :Rounding to two decimal places, we get the final answer: \(\boxed{15211.06}\).
