Answer:
Outside any special election, Seth will report $910 as interest income in the current year.
Step-by-step explanation:
Investment in Series EE savings bond on April 1 = $27,000
Redemption value of bonds by December 31 = $27,910
Interest income = $910 ($27,910 - $27,000)
The effective rate of interest = 3.37% ($910/$27,000 * 100) for nine months, with its annualized rate = 4.5% (3.37%/9 * 12).
