If an investor purchases the bond at face value ($500) and holds it until maturity, they will receive the face value of the bond plus the interest earned over the year.
The bond has a 2% yield, which means the interest for one year is:
\[ \text{Interest} = \text{Face Value} \times \text{Yield} = 500 \times 0.02 = 10 \text{ dollars} \]
At maturity, the bondholder will receive the face value of the bond plus the interest:
\[ \text{Total Payment at Maturity} = \text{Face Value} + \text{Interest} = 500 + 10 = 510 \text{ dollars} \]
Therefore, the bondholder should expect to receive $510.
