Concept:Payments to a creditor decrease both the liability and the cash balance.Explanation:In Lima's books, Dongo is a creditor because Lima owed Dongo money.When Lima pays D2,500 in cash, the liability to Dongo is reduced.A decrease in a liability is recorded by debiting the creditor's account.Cash goes out of the business, so the cash account is credited.Therefore, the double entry is: debit Dongo with D2,500 and credit cash with D2,500.Answer:Debit Dongo D2,500; credit cash D2,500.
