Answer: Please see the required journals below:
Mar. 17:
Debit Allowance for doubtful accounts $1,000
Credit Accounts receivable $1,000
July 29:
Debit Cash $1,000
Credit Bad debt recovery (income statement) $1,000
Explanation: On March 17, when $275 was received from Shawn and the remaining balance of $1,000 was written off, the allowance for doubtful accounts has to be debited since the company adopts the allowance method of accounting for uncollectible receivables. Note that the allowance account would have the required buffer to take care of this debit. Similarly, when the recovery was made, cash would be debited then the credit would default to income statement.
