Answer:
none of the above
Step-by-step explanation:
depreciation expense per year using straight line method = (purchase cost - residual value) / useful life = ($16,000 - $2,000) / 5 years = $14,000 / 5 = $2,800 per year
The straight line method for calculating depreciation expense is the simplest method that we can use, since the depreciation expense is the same for every year. Unlike double balance, sum of digits or any other kind of deprecation expense method which varies from year to year.
