Answer:
$60,000
Explanation:
Double declining method is a depreciation method used to expense the cost of an asset.
Depreciation expense using the double declining method = Depreciation factor × cost of asset
Deprecation factor = 2 (1/useful life) = 2(1/8) = 1/4
Depreciation expense in 2016 = 0.25 × $320,000 = $80,000
Net book value = $320,000, - $80,000 = $240,000
Deprecation expense in 2017 = 0.25 x $240,000 = $60,000
