Answer:
D) debit Supplies, $1,500; credit Supplies Expense, $1,500.
Explanation:
The first journal entry was:
Dr Supplies expense 4,000
Cr Cash 4,000
If at the end of the year the supplies inventory equals $1,500, then the supplies expense must decrease. Expenses have a debit balance, if we want to decrease them, we must credit them.
The adjusting entry would be:
Dr Supplies 1,500
Cr Supplies expense 1,500
This way the supplies account (asset) increases, while the expenses decrease.
