Final answer:
The adjusting entry to account for the $7,000 of used office supplies would involve debiting Office Supplies Expense and crediting Office Supplies Inventory by the same amount.
Step-by-step explanation:
The student's question pertains to an unrecorded expense of office supplies at year end. The question is asking for the proper adjusting entry that needs to be made if $7,000 worth of office supplies were used up but no entry was recorded. To correct this, the adjusting entry would debit Office Supplies Expense for $7,000 and credit Office Supplies Inventory for $7,000.
This would have the effect of increasing expenses and decreasing assets on the balance sheet, accurately reflecting the use of supplies during the period.
