Answer:
Cost of Goods Sold Dr.
To Supplies Expense
Explanation:
The journal entry for cost of goods sold should've been:
Cost of goods sold A/C Dr.
To Purchases A/C
(Being cost of goods sold expense recorded)
The wrong entry passed has been:
Supplies expenses A/C Dr.
To Purchases A/C
The rectifying (correcting) journal entry should be:
Cost of Goods Sold A/c Dr.
To Supplies Expenses A/C
(Being rectification entry for cost of goods sold recorded)
Cost of goods sold is an expense and expenses should be debited.
At the same time, purchase being a nominal account, crediting it would reduce the purchases balance.
Supplies expense was wrongly debited so it has been credited to cancel out the effect.
