How do I use the double-declining-balance method, a time-based method, to calculate the depreciation expense for Asset A in year 2017?

Depreciation Methods Vorst Corporation's schedule of depreciable assets at December 31, 2016, was as follows: Asset Cost Accumulated Acquisition Residual Depreciation Date Value $ 64,000 2015 $20,000 36,000 2014 10,000 A $100,000 B 55,000 70,000 33,600 2014 14,000 $225,000 $133,600 $44,000 Vorst takes a full year's depreciation expense in the year of an asset's acquisition and no depreciation expense in the year of an asset's disposition. The estimated useful life of each depreciable asset is 5 years. Vorst depreciates Asset A on the double-declining-balance method. How much depreciation expense should Vorst record in 2017 for Asset A? a. $25,600 b. $14,400 C. $6,400 d. $32,000
