Answer :
Answer:
$57,000
Explanation:
Step 1 : Depreciation Rate
Depreciation Rate = (Cost - Residual Value) ÷ Estimated Production
therefore,
Depreciation Rate = $14.00 per machine hour
Step 2 : Depreciation expenses
Depreciation expense = Depreciation Rate x Annual production
therefore
Year 1 = $42,000
Year 2 = $56,000
Year 3 = $70,000
Total = $168,000
Step 3 : Book Value
Book Value = Cost - Accumulated Depreciation
= $225,000 - $168,000
= $57,000
Conclusion :
book value at the end of year 3 is $57,000
