Answer:
1.a) Under the straight line method depreciation expense is as follows;
-Year 1 = $22,500.
-Year 2 =$ 22,500.
-Year 3 = $22,500.
b) Under the units-of-activity method depreciation expense is as follows;
-Year 1 = $28,500.
-Year 2 =$ 22,500.
-Year 3 = $16,500.
c) Under the double-declining-balance method depreciation expense is as follows;
-Year 1 = $48,000.
-Year 2 = $16,000.
-Year 3 = $3,500.
The total depreciation expense for the three years by each method is as follows;
- Units-of-activity method =Year 1+Year 2+Year 3
= 28,500+22,500+16,500=$67,500.
- Straight line method =Year 1+Year 2+Year 3
=22,500+22,500+22,500 =$67,500.
-The double-declining-balance =Year 1+Year 2+Year 3
=48,000+16,000+3,500 =$67,500.
2.The method that yields the highest depreciation expense for Year 1 is the double-declining-balance depreciation method,it yields $48,000. The units-of-activity method and the straight line method yields $28,500 and $22,500 respectively.
3. No method yields the most depreciation over the three-year life of the equipment. All the methods yield $67,500 at the end of the 3 years of useful life.
Step-by-step explanation:
1. a) Depreciation by straight line method.
Depreciable cost = Acquisition cost - Salvage value
Depreciable cost = 72,000 - 4,500 = $67,500.
Annual depreciation expense = Depreciable cost/ Useful life.
Annual depreciation expense = 67,500/ 3 = $22,500.
Annual depreciation expense for year two = 45,000/2= $22,500.
Annual depreciation expense for year two=22,500/1= $22,500 .
b) Depreciation by units of activity method.
Depreciable cost = Acquisition cost - Salvage value
Depreciable cost = 72,000 - 4,500 = $67,500.
Depreciation per unit of activity = depreciable cost/Total useful units
Depreciation per unit of activity = 67,500/18,000 = $3.75 per hour.
Depreciation expense for Year 1 = 76,000 × 3.75 = $28,500.
Depreciation expense for Year 2 = 6000 × 3.75 = $22,500.
Depreciation expense for Year 3 = 4,400 × 3.75 = $16,500.
b) Depreciation by the double-declining-balance.
Depreciable cost = Acquisition cost - Salvage value.
Depreciable cost = 72,000 - 4,500 = $67,500.
Annual depreciation expense = 67,500/ 3 = $22,500.
Depreciation rate = (annual depreciation /depreciable cost) × 100
Depreciation rate = (22,500 /67,500) × 100 = 33.333333%
Since it is double-declining we multiply the rate by 2 33.333333% × 2= 66.66667%.
Depreciation = Asset carrying value × depreciation rate.
Year 1 depreciation = 72,000 × 66.66667%=$48,000.
Year 1 depreciation = 24,000 × 66.66667%= $16,000.
Year 1 depreciation = 8,000 - 4,500 = $3,500.
2. Determining the method that yields the highest depreciation expense for Year 1.
The method that yields the highest depreciation expense for Year 1 is the double-declining-balance depreciation method,it yields $48,000. The units-of-activity method and the straight line method yields $28,500 and $22,500 respectively.
3. Determining accumulated depreciation using the 3 methods.
The accumulated depreciation using the straight line method
=Year 1+Year 2+Year 3 .
=22,500+22,500+22,500 =$67,500.
The accumulated depreciation using units-of-activity method
=Year 1+Year 2+Year 3 .
= 28,500+22,500+16,500=$67,500.
The accumulated depreciation using double-declining-balance.
=Year 1+Year 2+Year 3 .
=48,000+16,000+3,500 =$67,500.
No method yields the most depreciation over the three-year life of the equipment than the other. All the methods yield $67,500 at the end of the 3 years of useful life.
