Final answer:
The correct entry to record the write-off of Mendez, Inc.'s account using the allowance method is option C: Allowance for doubtful accounts, accounts receivable-- Mendez, Inc.
Step-by-step explanation:
The correct entry to record the write-off of Mendez, Inc.'s account using the allowance method is option C: Allowance for doubtful accounts, accounts receivable-- Mendez, Inc.
When using the allowance method, the write-off of an uncollectible account involves reducing the Accounts Receivable balance and the Allowance for Doubtful Accounts balance by the same amount.
This reflects the recognition that the specific account is unlikely to be collected. Option C correctly reflects this process by debiting Allowance for Doubtful Accounts and crediting Accounts Receivable-- Mendez, Inc.
