9. The following machines were purchased during 2013:
Machine A for $12,000 on April 7
Machine B for $8,000 on August 28
Machine C for $10,000 on November 5
Assuming that each machine has an estimated useful life of six years and a 10 percent residual value,
calculate total depreciation expense for 2013 (assume that the company depreciates the asset on
straight-line basis, reports on a calendar-year basis and rounds to the nearest month).
10. Oren Company’s air-conditioning system has just completed the eighth year of an estimated ten-year
life. The system cost $60,000 and now has accumulated depreciation of $48,000. At the beginning of
the ninth year, the company expects to spend $16,000 on a complete renovation of the system and
expects the total life of the system to be fifteen years. Neither the capacity of the system nor the
residual value was increased. The company uses the straight-line method to determine depreciation.
Determine the following: (a) the account debited for the cost of renovation, (b) the carrying value of
the system after renovation, and (c) the depreciation expense for the ninth year.
11. Guilford Company’s air-conditioning system has just completed the eighth year of an estimated
ten-year life. The system cost $30,000 and now has accumulated depreciation of $24,000. At the
beginning of the ninth year, the company expects to spend $8,000 on a complete renovation of the
system and expects the total life of the system to be fifteen years. Neither the capacity of the system
nor the residual value was increased. The company uses the straight-line method to determine
depreciation. Determine the following: (a) the account debited for the cost of renovation, (b) the
carrying value of the system after renovation, and (c) the depreciation expense for the ninth year.
