Answer:
Supplies Expense $3970 Dr
Supplies Account $3970 Cr
Explanation:
The adjusting entry is made at the end of the accounting period. If on the day of adjusting entry, the supplies account shows a higher balance then the supplies on hand, we will need to charge the difference between these two amounts to the supplies expense account and reduce the supplies account by the same amount.
The difference between supplies account and supplies on hand is 4850 - 880 = $3970
