### Explanation

To solve this problem, use the future value of an annuity formula, which calculates the future balance of a series of equal payments at regular intervals, compounded at a specific rate.

\[ FV = P \times \frac{{(1 + r/n)^{nt} - 1}}{{r/n}} \]

Where:
- \( P \) is the monthly deposit ($200)
- \( r \) is the annual interest rate (0.064)
- \( n \) is the number of times the interest is compounded per year (12)
- \( t \) is the total number of years (20)

This calculation will give you the total amount in the account after 20 years.
