Mayfair Co. allows select customers to make purchases on credit. Its other customers can use either of two credit cards: Zisa or Access. Zisa deducts a 3.0% service charge for sales on its credit card and credits the bank account of Mayfair immediately when credit card receipts are deposited. Mayfair deposits the Zisa credit card receipts each business day. When customers use Access credit cards, Mayfair accumulates the receipts for several days before submitting them to Access for payment. Access deducts a 2.0% service charge and usually pays within one week of being billed. Mayfair completes the following transactions in June. (The terms of all credit sales are 2/15, n/30, and all sales are recorded at the gross price.)
