Final answer:
The depreciation expense for the machinery for the two months from October 31, 2001, to December 31, 2001, using the straight-line method, is $3,500.
Step-by-step explanation:
Calculating Depreciation Expense
The question involves calculating the depreciation expense of machinery using the straight-line method of depreciation. The total cost of the machinery is $90,000, with an estimated salvage value of $6,000 and a useful life of 4 years. The depreciation expense is calculated as follows:
Annual Depreciation Expense = (Cost - Salvage Value) / Useful Life
Annual Depreciation Expense = ($90,000 - $6,000) / 4
= $21,000 per year
Since the machinery was purchased on October 31, 2001, and the depreciation expense must be recorded at December 31, 2001, we need to calculate the expense only for the months of November and December. Therefore, the depreciation expense for 2 months is:
Depreciation Expense for 2 months = Annual Depreciation Expense / 12 months * 2 months
Depreciation Expense for 2 months = $21,000 / 12 * 2
= $3,500
