Final answer:
The appropriate adjusting journal entry to establish the estimate for uncollectible accounts is to debit the Allowance for Uncollectible Accounts and credit Accounts Receivable by the estimated amount of $2,500.
Step-by-step explanation:
The appropriate adjusting journal entry to establish the estimate for uncollectible accounts is as follows:
Allowance for Uncollectible Accounts $2,500
Accounts Receivable $2,500
This entry records an increase in the allowance for uncollectible accounts and a decrease in accounts receivable by the estimated amount of $2,500. This adjustment reflects the company's expectation of not being able to collect that amount from its customers. The allowance for uncollectible accounts is a contra asset account that reduces the reported value of accounts receivable on the balance sheet.
