S10-5 (book/static) On February 28, 2017, Rural Tech Support purchased a copy machine for $ 53 comma 400. Rural Tech Support expects the machine to last for six years and to have a residual value of $ 3 comma 000. Compute depreciation expense on the machine for the year ended December 31, 2017, using the straight-line method.

$7,000

Explanation:

depreciation expense using straight line method = (purchase cost - salvage value) / useful life = ($53,400 - $3,000) / 6 years ) = $8,400 per year

since the machine was used for 10 months, the depreciation expense for 2017 = $8,400 x 10/12 = $7,000

the adjusting journal entry should be:
