Answer:
MNVK Corp.
Depreciation expense for 2021 = $24,000
Step-by-step explanation:
a) Data and Calculations:
Cost of computer system = $150,000
Purchase date = January 1, 2020
Estimated useful life = 10 years
Residual value = $10,000
Straight-line depreciation rate = 10%
Double-declining balance method rate = 10% * 2 = 20%
Depreciation expense for 2020 = $30,000 ($150,000 * 20%)
Balance after 2020 = $120,000 ($150,000 - $30,000)
Depreciation expense for 2021 = $24,000 ($120,000 * 20%)
b) The double-declining method is based on the straight-line depreciation rate, multiplied by 2. The method does not consider the residual value initially. It is towards the end of the useful life that the residual value is accounted for, to ensure that depreciation expense does not eat into it.
