To solve for the future value of Ryan's investment using compound interest, we’ll use the formula:

\[
A = P \left(1 + \frac{r}{n}\right)^{nt}
\]

where:
- $ A $ = the future value of the investment (the amount we are solving for),
- $ P $ = the principal investment amount (initial deposit), which is $5,900,
- $ r $ = the annual interest rate (decimal), which is 5% or 0.05,
- $ n $ = the number of times that interest is compounded per year, which is monthly (so $ n = 12 $),
- $ t $ = the number of years the money is invested, which is 11 years.

### Step-by-Step Calculation:

1. Substitute the values into the formula:

\[
A = 5900 \left(1 + \frac{0.05}{12}\right)^{12 \times 11}
\]

2. Calculate the monthly interest rate:

\[
\frac{0.05}{12} = 0.0041667
\]

3. Multiply the compounding periods per year by the number of years:

\[
12 \times 11 = 132
\]

4. Substitute back to get:

\[
A = 5900 \left(1 + 0.0041667\right)^{132}
\]

5. Calculate $ (1 + 0.0041667)^{132} $:

\[
A = 5900 \times (1.0041667)^{132}
\]

6. After calculating the power, you’ll find:

\[
A \approx 5900 \times 1.744
\]

7. Multiply to find the future value:

\[
A \approx 10289.60
\]

So, the amount in the account after 11 years will be approximately **$10,289.60**.

### Tip:
For accurate results, always remember to round intermediate values only at the final step to avoid rounding errors.

Ryan invested $5,900 in an account paying an interest rate of 5% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 11 years?
