a. What was the book value of the equipment at December 31, 2014, the end of the year?
b. Assuming that the equipment was sold on October 1, 2015, for $275,000, journalize the entries to record (1) depreciation for the nine months until the sale date, and (2) the sale of the equipment.
Answer:

a. Cost of equipment……………………………………………………………………………… $420,000
Accumulated depreciation at December 31, 2014
(4 years at $26,000* per year)……………………………………………………………… 104,000
Book value at December 31, 2014…………………………………………………………… $316,000
* ($420,000 – $30,000) ÷ 15 = $26,000
b.
(1) Depreciation Expense—Equipment 19,500
Accumulated Depreciation—Equipment 19,500
Equipment depreciation ($26,000 × 9/12 = $19,500).
(2) Cash 275,000
Accumulated Depreciation—Equipment* 123,500
Loss on Sale of Equipment 21,500
Equipment 420,000
* $104,000 + $19,500 = $123,500
