Final answer:
The total return for the past year is 259.91%.
Step-by-step explanation:
The total return for the past year can be calculated by finding the difference between the face value and the price you paid for the bond. The face value of the bond is $1000. The price you paid for the bond was $277.83. So the difference is $1000 - $277.83 = $722.17.
To calculate the total return as a percentage, divide the difference by the price you paid and multiply by 100.
Total return = ($722.17 / $277.83) * 100 = 259.91%.
