Detailed Answer
Answer (C) is correct. Under the double-declining balance method, the full cost of the asset, or $100,000, is depreciated, but not below salvage value. Because the straight-line rate for a 10-year asset is 10% (100% x 10), the double-declining balance rate is 20% (10% x 2). The first year’s depreciation is $20,000 ($100,000 x 20%), leaving a carrying amount for the second year of $80,000 ($100,000 - $20,000). The second year’s depreciation is thus $16,000 ($80,000 x 20%).
