Answer:
$20,408.16
Step-by-step explanation:
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor = 2 x (1/useful life) = 2/7
1st year= 2/7 x 100,000 = 28,571.43
book value = 100,000 - 28,571.43 = 71,428.57
2nd year = 2/7 x 71,428.57 = $20,408.16
