Answer:
(a) Dec 31 Depreciation Expense-Equipment 6300 Dr
Accumulated Depreciation-Equipment 6300 Cr
(b) Dec 31 Depreciation Expense-Equipment 525 Dr
Accumulated Depreciation-Equipment 525 Cr
Step-by-step explanation:
(a) The normal entry to record the depreciation expense is always to debit the depreciation expense account for the relevant asset as the expense is increasing and credit the contra asset account of Accumulated depreciation created against that particular asset.
If the adjustments are prepared once a year, that means the depreciation expense has not been recorded and charged for the whole year and it will be charged whenever the adjustments are made. So, on 31 december when the adjustments are made, we will charge the whole year's deprecation on equipment as depreciation expense and credit accumulated depreciation by the same amount ( in this case 6300 for the whole year).
(b) If the adjustments are made on a monthly basis that means that every month the relevant month's depreciation is charged and recorded as an expense. Assuming the depreciation is a straight line basis, we simply charge the December's depreciation on 31 December which is calculated as,
6300 / 12 = 525 / month
