Given: Total cost of computer system= $50000.
Residual value= $5000.
Useful life= 5 years.
Now, calculating depreciation expense as per double-declining balance method.
[tex]Depreciation\ expense= (cost- Accumlated\ depreciation)\times \frac{2}{useful\ life}[/tex]
⇒ [tex]Depreciation\ expense= (\$ 50000- \$0)\times \frac{2}{5}[/tex]
⇒ [tex]Depreciation\ expense= \$ 50000\times \frac{2}{5}[/tex]
∴ [tex]Depreciation\ expense= \$ 20000[/tex]
Hence, $20000 is the depreciation expense for first year as per double-declining balance method.
