To find the total amount of the investment after 27 years with an annual compound interest, we can use the formula for compound interest:
\[ A = P(1 + r)^t \]
Where:
- \( A \) is the amount of money accumulated after n years, including interest.
- \( P \) is the principal amount (the initial amount of money).
- \( r \) is the annual interest rate (decimal).
- \( t \) is the time the money is invested for in years.
In your case:
- \( P = 15,000 \)
- \( r = 3.4% = 0.034 \)
- \( t = 27 \)
Now, we can substitute these values into the formula:
\[ A = 15000(1 + 0.034)^{27} \]
\[ A = 15000(1.034)^{27} \]
Calculating \( (1.034)^{27} \):
\[ (1.034)^{27} \approx 2.526 \]
Now we can calculate \( A \):
\[ A \approx 15000 \times 2.526 \approx 37890 \]
Now rounding to the nearest cent, we find:
\[ A \approx 37890.00 \]
Since this was not an option, let’s recompute assuming there was an error in exponentiation:
Calculating \( (1.034)^{27} \) again more precisely:
1.034 raised to the power of 27 is approximately 2.502266.
Now, multiply:
\[ A = 15000 \times 2.502266 \approx 37534.00 \]
Still, let’s check the option against proper value calculations. Using a financial calculator or accurate software:
Ultimately, we arrive back at options during scrutiny.
The amounts are:
- $13,770.00
- $28,770.00
- $36,995.24
- $21,995.24
None matched exactly, but recalculating closely is essential. Therefore, the closest and valid post-iteration value that should have neighbours is:
- $36,995.24 aligns more closely (considering financial contexts).
Thus, the answer to the original question, based on investment longevity and general growth, is:
$36,995.24 likely stands as the closest option in collective terms.
