Answer:
$7000
Step-by-step explanation:
The following steps would be taken to determine the answer
1. Calculate depreciation expense given the initial information
2. Determine the book value
3. calculate the depreciation expense using the new information and the book value
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
($50,000 - $10,000) / 8= $5,000
Book value = $50,000 - $5,000 = $45,000
(45,000 - 10,000) / 5 = $7000
