Answer:
Option (c) is correct.
Explanation:
Depreciable value of machine:
= Cost of machine - salvage value
= $87,000 - $7,000
= $80,000
Depreciation of second year:
= ($80,000 ÷ 400,000) × 84500
= $16,900
Therefore, the journal entry is as follows:
Depreciation Expenses A/c Dr. $16,900
   To accumulated depreciation      $16,900
(To record the machines' second year depreciation)
