Answer:
Depreciation expense for the first year under each method is,
1. Straight line method = $2100
2. Double declining balance method = $5000
3. Activity based method = $3360
Explanation:
1.
The straight line method of depreciation charges a constant amount of depreciation expense through out the useful life of the asset. The formula for depreciation expense per year under this method is,
The depreciation rate under this method is,
Depreciation rate = 100% / 10 = 10%
Depreciation expense = (Cost - Salvage value) / estimated useful life
Depreciation expense = (25000 - 4000) / 10 = $2100 per year
2.
Double declining method is an accelerated method of allocating the depreciation expense. The initial years depreciation is higher in this method. The formula for depreciation expense per year under this method is,
Depreciation expense = 2 * Straight line rate * Carrying value of asset at start of period
Depreciation expense = 2 * 0.1 * 25000 = $5000 for the first year
3.
Under activity based method, we simply allocate depreciation based on the activity level for which asset is used this year. The formula for this method is,
Depreciation expense = Units of activity for the year * (Cost - Salvage value) / Total estimated life in units of activity
Depreciation expense = 1600 * (25000 - 4000) / 10000
Depreciation expense = $3360 for the first year
