Final answer:
The amount of accumulated depreciation at December 31, 2023, using the straight-line method would be $108,572.
Step-by-step explanation:
To calculate the amount of accumulated depreciation using the straight-line method, we need to determine the annual depreciation expense. The formula for straight-line depreciation is:
Annual depreciation expense = (Cost of machinery - Salvage value) / Useful life
Using the given information:
Cost of machinery = $440,000
Salvage value = $60,000
Useful life = 7 years
So, the annual depreciation expense would be:
Annual depreciation expense = ($440,000 - $60,000) / 7 = $54,286
To find the accumulated depreciation at December 31, 2023, we need to calculate the total depreciation expense from the date of purchase to that date. Since the machinery was purchased on January 1, 2022, there would be 2 years of depreciation by December 31, 2023.
Accumulated depreciation = Annual depreciation expense x Number of years = $54,286 x 2 = $108,572
Therefore, the amount of accumulated depreciation at December 31, 2023, would be $108,572.
