Final answer:
The total bond interest expense over the life of the bonds is $480.
Step-by-step explanation:
To calculate the total bond interest expense over the life of the bonds, we need to first calculate the annual interest payment. In this case, the bond was issued for $3,000 at an interest rate of 8%, so the annual interest payment is $3,000 * 8% = $240.
As the bond is a two-year bond, the total bond interest expense over the life of the bonds is the sum of the annual interest payments for each year: $240 + $240 = $480.
