Answer:
a. Office Supplies Expense a/c Dr. $750
Step-by-step explanation:
We are provided that office supplies are recorded as an expense, in that case entry will be:
Office Supplies Expense A/c Dr.
To Cash A/c
After this, there is a valuation of closing balance of supplies in hand.
As per books = $4,000
As per inventory of supplies in hand = $4,750
The difference = $4,750 - $4,000 = $750
This will be recorded in Office supplies expense as in this account only the supplies are recorded.
Therefore correct option is
a. Office Supplies Expense a/c Dr. $750
