Step-by-step explanation:
The entry to close the Income Summary account at the end of the year, after revenue and expense accounts have been closed, is option 2) Debit T. Westmont, Capital 63,300; credit Income Summary 63,300.
To close the Income Summary account, we need to transfer the net income (revenues - expenses) to the owner's capital account. In this case, the net income is $81,300 ($185,000 - $103,700). Since the owner withdrew $18,000 from the business, we subtract that from the net income to get $63,300. We debit T. Westmont, Capital for $63,300 and credit Income Summary for the same amount.
