Final answer:
Depreciation for the equipment should be calculated using the straight-line, double-declining-balance, or units-of-production depreciation methods, resulting in $2,700, $5,600, or $2,700 respectively for the period from October 1 to December 31.
Step-by-step explanation:
The calculation of depreciation for the equipment involves determining the reduction in value over a given period using different methods of depreciation. Each method takes into account the cost of the equipment, its estimated residual value, and the useful life or usage of the equipment.
Straight-Line Depreciation
The straight-line method divides the depreciable base of the equipment, which is the original cost minus the residual value, evenly over its useful life. In this case:
Depreciable base = $56,000 - $2,000 = $54,000
Annual depreciation = $54,000 / 5 years = $10,800
Depreciation for Oct 1 to Dec 31 (3 months) = $10,800 * (3/12) = $2,700
Double-Declining-Balance Depreciation
For the double-declining-balance method, the depreciation rate is twice the straight-line rate and is applied to the book value of the asset at the beginning of the year. However, since the purchase was made during the year, only a fraction of the year's depreciation applies:
Straight-line rate = 1 / 5 years = 20%
Double-declining rate = 20% * 2 = 40%
Depreciation for Oct 1 to Dec 31 = $56,000 * 40% * (3/12) = $5,600
Units-of-Production Depreciation
The units-of-production method determines depreciation based on usage. The cost per unit of production is based on the total number of productive hours over the life of the asset:
Depreciation per hour = ($56,000 - $2,000) / 20,000 hours = $2.70 per hour
Depreciation for 1,000 hours used = $2.70 * 1,000 = $2,700
