Mountain view resorts purchased equipment at the beginning of 2021 for $46,000. residual value at the end of an estimated four-year service life is expected to be $6,900. the machine operated for 1,600 hours in the first year and the company expects the machine to operate for a total of 10,000 hours over its four-year life. calculate depreciation expense for 2021, using each of the following depreciation methods: (1) straight-line, (2) double-declining-balance, and (3) activity-based.

Straight line depreciation expense = $9,775

Double declining method = $23,000

unit of production method = $6,256

Explanation:

Depreciation expense is used to expense the cost of asset.

Depreciation expense using the straight line depreciation method = (cost of the equipment - Salvage value) / useful life

($46,000 - $6,900) / 4 = $9,775

The depreciation expense in 2021 is $9,775.

Depreciation expense using the double declining method = acceleration factor × net book value

Acceleration factor = 2×(1/useful life)

2(1/4) = 0.5

= 0.5 × $46, 000 = $23,000

Depreciation expense using the double declining method = $23,000

Depreciation expense using the unit of production method =Total use in a given period × [( Cost - Salvage value)/ total productive capacity]

($46,000 - $6,900) /10,000 = $3.91 × 1600 =$6,256

Depreciation expense using the unit of production method = $6,256

I hope my answer helps you.
