1. Identify the formula for compound interest: A = P \left(1 + \frac{r}{n}\right)^{nt}

- Where:

- \(A\) is the amount of money accumulated after n years, including interest.

- \(P\) is the principal amount (the initial amount).

- \(r\) is the annual interest rate (decimal).

- \(n\) is the number of times that interest is compounded per year.

- \(t\) is the time the money is invested for in years.

2. Substitute the given values into the formula:

- \(P = 8000\),

- \(r = \frac{6}{100} = 0.06\),

- \(n = 12\),

- \(t = 10\).

3. Calculate the compound interest:

A = 8000 \left(1 + \frac{0.06}{12}\right)^{12 \times 10}

4. Compute the value inside the parentheses:

1 + \frac{0.06}{12} = 1 + 0.005 = 1.005

5. Raise the result to the power of \(120\) (since \(12 \times 10 = 120\)):

1.005^{120} \approx 2.040160365

6. Multiply by the principal:

A=8000\times2.040160365\approx14555.17

7. The certificate will be worth $14555.17 after 10 years.
