Final answer:
Davis Hardware should record the sale of merchandise, costing $620 and sold for $950 on account, by debiting Accounts Receivable and crediting Sales Revenue.
Step-by-step explanation:
Davis Hardware, using a perpetual inventory system, should record the sale of merchandise, costing $620 and sold for $950 on account, by debiting Accounts Receivable and crediting Sales Revenue. This is because the sale is made on account, meaning the customer will pay at a later date, so the amount owed is recorded as an account receivable. The revenue from the sale is credited to Sales Revenue.
