Answer:
A) Dr Supplies Expense $2,600
Cr Supplies $ 2,600
Explanation:
The supplies account had an opening balance of $ 2400. Purchases were made of $ 3000 so the total debit balance was $ 5400. The year end showed a debit balance of $ 2800.
So $ 5400- $ 2800= $ 2600 Supplies were used and credited .
An expense account would be used to show this so
Supplies Expense is debited with $ 2600 and
Supplies Account is credited with $ 2600 showing a net debit balance of $ 2800 at the end of the year.
