Answer:
C. Debit Service Fee Expense for $6
Explanation:
McGregor only uses the services of the Credit Card company for their own activities, therefore, aside from the income of the service provided of $200, the credit card company will charge McGregor for the use of credit card services by the customer.
As such, since it is the decision of the customer to pay with a credit card, then the customer must bear the service fee expense of 3% of the cost of the service which is $6. Hence, Option C is correct. It means aside the $200 for the service, there is a need to debit service fee expense for $6
Option D is wrong because only $200 is service revenue, it has to be clearly stated that the 3% of $6 is different from the service revenue and should be debited as service fee.
If the customer is reluctant to make the payment, then there is an allowance to pay cash instead of using the credit card service.
