The amount of depreciation for the second full year, using the double-declining-balance method is $20,400.
Depreciation is a method used in expensing the value of an asset.
Double declining depreciation expense = [2 x (1/useful life of the asset)] x cost of the asset
Depreciation expense in year 1 = 2/5 x $85,000 = $34,000
Book value at the beginning of year 2 = $85,000 - $34,000 = $51,000
Depreciation expense in year 2 = 2/5 x $51,000 = $20,400
