Cash Book Error

Per Co's cash book showed a debit balance of $8,210 at 31 May 20X0. The following items have not been recorded in the cash book: (1) Bank interest received of $95 (2) A cheque received for $60 was dishonoured by the bank (3) Direct debit payments of $1,045 What is the correct cash book balance at 31 May 20X0? My answer is $7200. Please explain to me if i'm wrong Mr. Maffot. Thanks
