Answer: The depreciation expense that will be recorded for the furniture for the first year ended December 31 is $825.
Explanation: Straight-line mwthod of depreciation is:
(Acquisition value minus salvage value) / No of years
Per the question, the acquistion value of the new furniture is $19,000 while the salvage value is $2,500. The number of years is 5 years.
Then yearly depreciation would be ($19,000 - $2,500) / 5 years = $3,300.
Note that the furniture was purchased on September 30. To arrive at the depreciation expense that will be recorded as at December 31, you need to pro rate the yearly depreciation of $3,300.
September 30 to Decemer 31 is 3 months. So the total depreciation expense will be $3,300 * 3 / 12 = $825.
