A business maintains control accounts as a part of its double entry system. The balance of the purchases ledger control account is $8232. However, this does not agree with the total of balances in the purchases ledger. The following account for the difference. 1 An entry in the purchases returns journal for $72 has been posted to the credit side of the individual trade payable's account in the purchases ledger. 2 An entry for discounts received in the cash book for $54 has been debited to the individual trade payable's account in the purchases ledger as $45. What is the total of balances in the purchases ledger before these errors are corrected?
