Answer:
8750
4000
$74,060
39,300
Explanation:
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
(117,900 - 12,900) / 5 = $21,000
the machine was used for 5 months in 2017. the depreciation expense in 2017 = 5/12 x $21,000 = $8750
b. Activity method based on hours worked = (hours worked that year / total hours of the machine) x (Cost of asset - Salvage value)
(800 / 21,000) x (117,900 - 12,900) = $4000
c. Sum-of-the-year digits = (remaining useful life / sum of the years ) x (Cost of asset - Salvage value)
remaining useful life in 2018 = (4 + 7/12) + 3 + 2 + 1 = 10.58
10.58 / 15 x (117,900 - 12,900) = $74,060
