I keep getting the same part wrong, but I dont know why.

Exercise 8-3 At the beginning of the current period, Blossom Company had balances in Accounts Receivable of $191,500 and in Allowance for Doubtful Accounts of $9,890 (credit). During the period, it had net credit sales of $733,600 and collections of $767,780. It wrote off as uncollectible accounts receivable of $7,149. However, a $2,957 account previously written off as uncollectible was recovered before the end of the current period. Uncollectible accounts are estimated to total $25,440 at the end of the period (Omit cost of goods sold entries.)
