Final answer:
To prepare the year-end journal entry for depreciation on December 31, 2024, use the double-declining balance method. Calculate the depreciation expense using the formula and information provided, and then record the entry.
Step-by-step explanation:
To prepare the year-end journal entry for depreciation on December 31, 2024, we need to calculate the depreciation expense using the double-declining balance method. The formula for this method is:
Depreciation Expense = (Book Value - Residual Value) / Useful Life
Using the information provided, the book value of the equipment on January 1, 2024, would be $36,000 ($40,000 cost - $4,000 previous accumulated depreciation) and the revised useful life is 10 years with a revised residual value of $900.
Therefore, the depreciation expense for 2024 would be:
Depreciation Expense = ($36,000 - $900) / 10 = $3,510
The year-end journal entry for depreciation on December 31, 2024, would be:
Depreciation Expense $3,510
Accumulated Depreciation $3,510
