Final answer:
The journal entry to record the first year's amortization for the patent is a debit to Amortization Expense and a credit to Accumulated Amortization.
Step-by-step explanation:
The journal entry to record the first year's amortization for the patent will be:
A. Debit Amortization Expense $25,000, credit Accumulated Amortization $25,000
Since the patent has a useful life of 6 years, the $150,000 cost will be spread evenly over those 6 years. Each year, $25,000 will be recorded as amortization expense, reducing the value of the patent. Accumulated amortization is a contra-asset account that tracks the total amortization expense incurred over time. By crediting Accumulated Amortization, we are reducing the value of the patent on the balance sheet.
