Updating the sales ledger control account balance Steps:

• Start with opening debit balance of $1750.
• Add credit sales of $215 to get$1965.
• Subtract sales returns of $360 to get$1605.
• Subtract cheques received of $1480 to get$125.
• Subtract irrecoverable debts written off of $280 to get -$155; the $5 lacks clear context for entry (e.g., interest or discount). Not enough information to confirm a positive debit balance, as transactions result in overpayment/negative, and$5 phrasing is ambiguous.

Final answer: Not enough information.
