Archer Co. allows select customers to make purchases on credit. Its other customers can use either of two credit cards: Commerce Bank or Aztec. Commerce Bank deducts a 3% service charge for sales on its credit card and immediately credits the bank account of Archer when credit card receipts are deposited. Archer deposits the Commerce Bank credit card receipts each business day. When customers use the Aztec card, Archer accumulates the receipts for several days and then submits them to Aztec for payment. Aztec deducts a 2% service charge and usually pays within one week of being billed. Archer completed the following transactions in August (terms of all credit sales are 2/10, n/30; and all sales are recorded at the gross price).
