Answer:
a.
The depreciable cost is $170500
b.
The depreciation rate is $3.1 per mile
c.
The depreciation expense for the year is $13640
Explanation:
a.
The depreciable cost is the cost of the asset that qualifies to be charged as depreciation expense over the estimated useful life of the asset. The depreciable cost is calculated as follows,
Depreciable cost = Cost - Residual Value
depreciable cost = 180000 - 9500 = $170500
b.
The depreciation rate under unit of activity method is the amount of depreciation that will be charged per unit of the asset usage.
The depreciation rate = Depreciable cost / estimated useful life in units of activity
The depreciation rate = 170500 / 55000 = $3.1 per mile
c.
The units of activity depreciation for the year can be calculated by multiplying the depreciation rate per unit by the activity for the year in unit terms.
Depreciation expense for the year = 3.1 * 4400 = $13640
