A companys year-end balance in accounts receivable is $2,400,000. The allowance for uncollectible accounts had a beginning-of-year credit balance of $40,000. An aging of accounts receivable at the end of the year indicates a required allowance of $48,000. If bad debt expense for the year was $50,000, and if credit sales for the year were $7,900,000, and $7,200,000 was collected from credit customers, what was the beginning-of-year balance in accounts receivable?
