Answer:
The adjusting entry will be:
Dr Doubtful Debt expenses $3,200
Cr Allowance for doubtful Debt $3,200
(to record the estimated allowance for doubtful debt at the end of the period)
Step-by-step explanation:
The balance of Allowance for Doubtful Debt is estimated at 4% of receivables which is calculated as: 100,000 x 4% = $4,000.
Because the balance of Allowance for Doubtful Debt is $800 (credit) before adjustment entry, an entry is needed to rise the balance of Allowance for Doubtful Debt from $800 to $4,000, or Credit $3,200 to Allowance for Doubtful Debt.
As a result, Doubtful Debt expenses will be debited for $3,200 while Allowance for doubtful Debt will be credited for $3,200.
