Answer:
The adjusting entry is:
Debit Depreciation Expense - Equipment $1,800
Credit Accumulated Depreciation - Equipment $1,800
To record depreciation expense.
Step-by-step explanation:
The adjusting journal entry records the depreciation expense for the year and adds the expense to the accumulated depreciation account. The accumulated depreciation account is a contra account to the Equipment account. The purpose that this contra account serves is to keep the Equipment account at its cost value while the gradual write-off of its value is reflected in an opposite account.
