Answer:
Purchasing cost of computer = $6,400
useful life of computer = 5 year
salvage value = $2,200
Straight line depreciation per year:
= (Cost - Salvage value) ÷ Useful life
= ($6,400 - $2,200) ÷ 5
= $4,200 ÷ 5
= $840
Therefore, the journal entry is follows:
Depreciation expense A/c Dr. $840
To accumulated depreciation A/c $840
(To record the depreciation expense)
