Answer:
$7,621.72
Step-by-step explanation:
The equation that describes the future value (FV) of an investment (P) at an interest rate (r) for a period of n years, compounded semi-annually is:
![FV = P*(1+(r)/(2))^(2n)](https://img.qammunity.org/2021/formulas/business/college/xcv1w8j2g2f508aba6ot0rn1f82iv9p87r.png)
The amount required to yield $8,250 after 2 years at a rate of 4% per year is:
![8,250 = P*(1+(0.04)/(2))^(2*2) \\P=\$7,621.72](https://img.qammunity.org/2021/formulas/business/college/7sfmdrxqjomzsfqji4uoj47ydo0jxryxpr.png)
