## Prompt

You deposit $1,000 at 5% interest compounded annually. What is the balance after 3 years? Round to the nearest cent and show your work.

## Response

Using the compound interest formula:

\[
A = P(1+r)^t
\]

\[
A = 1000(1+0.05)^3
\]

\[
A = 1000(1.05)^3 = 1157.625
\]

Rounded to the nearest cent, the balance after 3 years is **\$1,157.63**.
