8. A machine with a cost of $64,000 has a useful life of 10 years, an estimated residual value of
$2,000 and is depreciated by the straight-line method. At the beginning of year 4, the remaining
useful life is estimated to be 3 years and the residual value is estimated to be $4,000.
What is the amount of depreciation for year 1?
What is the book value of the machine at end of year 3?
What is depreciation expense for year 4?
9. A company purchased a photocopy machine for $15,500. It has a useful life of 4 years or 725,000
copies and a residual value of $1,000. During the second year 118,000 copies were made.
Compute depreciation for the second year under each of the following methods: (a) straight-line,
(b) units-of-production, and (c) declining-balance.
$3,625 (15,500 – 1,000) / 4
$2,360 (15,500 – 1,000) (118,000 / 725,000)
$3,875 (15,500 – 7,750) 50%
(a)
$6,200 = (64,000 – 2,000) / 10
$45,400 = 64,000 – (6,200 3)
(c)
$13,800 = (45,400 – 4,000) / 3
