# Find the final balance of an account with 820 dollars and annual 4% interest for 3 years

\$29.10****
\$98.40
\$852.80
\$918.40

## To find the final balance of an account with \$820 and an annual interest rate of 4% for 3 years, you can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:
A is the final balance
P is the principal amount (initial balance)
r is the annual interest rate (in decimal form)
n is the number of times the interest is compounded per year
t is the number of years

In this case, the principal amount (P) is \$820, the annual interest rate (r) is 4% (or 0.04 in decimal form), the number of times the interest is compounded (n) is generally not given, so we'll assume it's compounded annually, and the number of years (t) is 3.

A = 820(1 + 0.04/1)^(1*3)
A = 820(1 + 0.04)^3
A = 820(1.04)^3
A = 820(1.124864)
A ≈ 920.35

So, the final balance of the account after 3 years would be approximately \$920.35.

None of the given options match the calculated final balance.
