Answer:
Debit Amortization expense $33,300
Credit Accumulated amortization $33,300
(To record amortization expense for the first year)
Step-by-step explanation:
Using the straight-line amortization, the applicable formula is: Cost / Estimated useful life
Amortization = $333,000 / 10 years = $33,300
The accumulated amortization and the amortization expense will be the same in the first year. So, the net book value of the patent is $333,000 - $33,300 = $299,700
