Burchells Ltd owns a machine that originally cost $36 000. It has been depreciated using the straight-line method for three years, giving an accumulated depreciation of $15 000 (the salvage value was estimated at $6000 and the useful life at six years). At the beginning of the current financial year its carrying value was therefore $21 000. It has been decided by the directors to revalue it to fair value, which has been assessed to be $38 000. The salvage value and useful life are considered to be unchanged. What are the appropriate entries to record the revaluation using the net-amount method and the depreciation expense for the current year (rounded to the nearest dollar)?
