Answer:
Raining Company and Tanning Company
An Uncollectible Expense of $17,500 will be credited to the Allowance for Doubtful Accounts to bring the credit balance to $20,000.
Step-by-step explanation:
Since the accounts receivable balance is $200,000, there is nothing to do with the credit sales of $1,300,000.
The Allowance for Doubtful Accounts after adjustment should have a credit balance of $20,000 ($200,000 x 10%).
With a credit balance of $2,500 before adjustment, it will be adjusted (credited) with Uncollectible Expense of $17,500. This brings the adjusted balance to $20,000 which represents 10% of the accounts receivable balance of $200,000.
Note that the Allowance for Doubtful Accounts is a contra (credit) account to the Accounts Receivable account. This allowance is a way to prudently provide for credit risk as required by Generally Accepted Accounting Principles.
