Answer:
$24,000
Step-by-step explanation:
Calculation to determine the machines' first year depreciation under the double-declining-balance method.
Using this formula
Depreciation Expense = (Cost - Salvage Value)/Estimated Useful Life
Let plug in the formula
Depreciation Expense = ($135,000 - $15,000)/5
Depreciation Expense=$120,000/5
Depreciation Expense= $24,000
Therefore the machines' first year depreciation under the double-declining-balance method is $24,000
