Step-by-step explanation:
The adjusting journal entry is as follows
Bad Debts Expense Dr. $3,200
To Allowance for Doubtful Accounts $3,200
(Being the bad debt expense is recorded)
The computation is shown below:
= Account receivable balance × estimated percentage - credit balance of allowance for doubtful debts
= $100,000 × 4% - $800
= $4,000 - $800
= $3,200
