Answer:
A) Debit Accounts Receivable, $225; credit Fees Earned, $225
Step-by-step explanation:
Willis owes Jefferson $225 (= 15 hours x $15 per hour).
The accounts receivable is debited because it represents money owed to Jefferson. Since it is an asset account and it increases, it should be debited.
Fees earned is a revenue account and since it increases, it should be credited.
