<br>
4% annual interest compounded semi-annually means 2% interest every 6 months.<br>
7 years compounded semi-annually means 14 compounding periods.<br>
The balance after 7 years is<br>
{{{2000(1+.02)^14}}}<br>
Use a calculator.<br>
Then of course the interest earned is the final balance, minus the original $2000.
