8-19. A warehouse has been acquired by a company at a total cost of $200,000, $50,000 of which was the appraised value of the land. The remaining useful life is estimated to be 15 years with a zero salvage value for the building. Of course, land is not depreciated and in the books of account is carried at its original cost. Determine the depreciation charge for the 10th year and the book value at the end of 10 years for the entire property if the building is depreciated by (a) the straight- line method, (b) the sum-of-years-digits method, and (c) the double-rate declining- balance method. hlin ccountant nurchased nd
