a) Straight line method b) Units-of-activity method c) Double-Declining
Year 1 $96,900 $135,600 $211,200
Year 2 $96,900 $81,396 $105,600
Year 3 $96,900 $108,528 $52,800
Explanation:
a) Data and Calculations:
Cost of equipment purchased on January 8 = $422,400
Expected useful life = 4 years or 7,600 operating hours
Residual value = $34,800
Depreciable amount = $387,600 ($422,400 - $34,800)
Straight-line Depreciation Expense per year = $96,900 ($387,600/4)
Units-of-activity method Depreciation Expenses:
Depreciation rate per hour = $51 ($387,600/7,600)
Period Hours Depreciation Expense
Year 1 2,660 $135,600 (2,660 * $51)
Year 2 1,596 $81,396 (1,596 * $51)
Year 3 2,128 $108,528 (2,128 * $51)
Year 4 1,216 $62,016 (1,216 * $51)
Double-declining-balance method:
Depreciation rate per year = 50% (100%/4 * 2)
Year 1 = $211,200 ($422,400 * 50%)
Year 2 = $105,600 ($211,200 * 50%)
Year 3 = $52,800 ($105,600 * 50%)
Year 4 = $18,000 ($52,800 - $34,800)
