Answer: See explanation
Step-by-step explanation:
From the question, we are given the information that on December 12, the company receives a $540 check from Chad Thomas in settlement of Thomas's $1,280 outstanding accounts receivable, then the journal entry based on the above will be:
December 12:
Debit Cash $540
Debit Allowance for doubtful account $740
Credit Account receivable $1280
Note that the allowance for doubtful account was calculated as:
= Account receivable - Cash
= $1280 - $540
= $740
