Sue and Sam Ristic own Club Fab. From its inception, Club Fab has sold merchandise on either a cash or credit basis, but no credit cards have been accepted. During the past several months, the Ristics have begun to question their credit-sales policies. First, they have lost some sales because of their refusal to accept credit cards. Second, representatives of two metropolitan banks have convinced them to accept their national credit cards. One bank, City National Bank, has stated that
(1) Its credit card fee is 4% and
(2) It pays the retailer 96 cents on each $1 of sales within 3 days of receiving the credit card billings.
The Ristics decide that they should determine the cost of carrying their own credit sales. From the accounting records of the past 3 years, they accumulate these data:



Credit and collection expenses as a percentage of net credit sales are as follows: Uncollectible accounts 1.6%, billing and mailing costs .5%, and credit investigation fee on new customers .2%. Sue and Sam also determine that the average accounts receivable balance outstanding during the year is 5% of net credit sales. The Ristics estimate that they could earn an average of 10% annually on cash invested in other business opportunities.
