Answer:
$207,500
$155,625
$116,719
Explanation:
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor = 2 x (1/useful life) = 2/8 = 1/4
1 = $830,000 / 4 = 207,500
book value $830,000 - 207,500 = 622,500
2 = 622,500 / 4 = 155,625
book value = 622,500 - 155,625 = 466875
3 466875 / 4 = 116,718.75 = 116,719
