To calculate the total interest expense for the given bond amortization schedule, you need to sum up all the "Interest Expense" amounts listed in each period.

Here are the steps:

1. Interest Expense for October 1, 2023 = $5,335
2. Interest Expense for April 1, 2024 = $5,313
3. Interest Expense for October 1, 2024 = $5,291
4. Interest Expense for April 1, 2025 = $5,268
5. Interest Expense for October 1, 2025 = $5,245
6. Interest Expense for April 1, 2026 = $5,222

Now, summing up these values:

$5,335 + 5,313 + 5,291 + 5,268 + 5,245 + 5,222 = 31,674$

However, since you mentioned that 31,674 is not the correct answer, it seems we need to investigate further. This could indicate that part of the question is missing or misunderstood, or perhaps some interest amounts are omitted. You may want to confirm the periods or consider any other interest components over the remaining bond periods.

Would you like to go through further details or check the complete amortization? Here are 5 potential questions:

1. Do we have the complete bond amortization schedule for all periods?
2. Was the bond issued at a premium or discount, affecting the amortization method?
3. Should we include additional adjustments for any missing interest payments?
4. What was the method used to calculate the interest expense—effective interest method or straight-line method?
5. Are there any other costs or bond-related fees not covered in this partial schedule?

Tip: When calculating bond interest expense using amortization, ensure the amortization schedule matches the method used (effective vs. straight-line) and covers the entire bond period.
