To calculate the future value of $6,000 earning 7% interest compounded quarterly for 9 years, we can use the formula for compound interest:
\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \]
Where:
- \( A \) is the future value of the investment
- \( P \) is the principal amount (the initial investment) = $6,000
- \( r \) is the annual interest rate (in decimal form) = 7% = 0.07
- \( n \) is the number of times interest is compounded per year = 4 (quarterly)
- \( t \) is the time the money is invested for, in years = 9
Plugging in the values:
\[ A = 6,000 \left(1 + \frac{0.07}{4}\right)^{4 \times 9} \]
\[ A = 6,000 \left(1 + \frac{0.07}{4}\right)^{36} \]
\[ A = 6,000 \left(1 + 0.0175\right)^{36} \]
\[ A = 6,000 \left(1.0175\right)^{36} \]
Using a calculator:
\[ A \approx 11,204.44 \]
Therefore, the future value of $6,000 earning 7% interest compounded quarterly for 9 years is approximately $11,204.44.
