Final answer:
Alejandro will receive a total return of $5400 when the bond is redeemed at maturity, with a total return on investment of $600.
Step-by-step explanation:
In this case, Alejandro bought the bond at a 4 percent discount from the face value of $5000, so he paid 96% of the face value, which is $5000 x 0.96 = $4800.
The bond pays 4 percent annual interest, which is $5000 x 0.04 = $200 per year. Since there are four semiannual payments, each payment will be $200/2 = $100.
Over the two-year term of the bond, Alejandro will receive a total of four semiannual payments, which amounts to $100 x 4 = $400 in interest payments.
When the bond is redeemed at maturity, Alejandro will receive the face value of $5000 plus the interest payments of $400, for a total return of $5000 + $400 = $5400 in dollars.
The total return on investment is calculated by subtracting the initial investment of $4800 from the total return of $5400, which gives $5400 - $4800 = $600.
