Answer: The journal entries for each of the transactions are:
a) Debit Credit
Bad debt expense $10,550
Allowance for doubtful accounts $10,550
b) Debit Credit
Allowance for doubtful accounts $1,100
Accounts receivable $1,100
Step-by-step explanation:
a) There was already an existing un-adjusted balance in the allowance for doubtful accounts of $10,800, meanwhile Blackhorse has estimated the amount to be $21,350 based on aging method. Simply subtract $10,800 from the $21,350 to arrive at $10,550. The above entries apply to recognize this additional provision.
b) Subsequent to year end, there was a write-off of $1,100, this means the accounts receivable balance would be reduced by this amount; same applies to the buffer (allowance account). The entries above apply.
