Answer:
The answer is: bad debt expense at the end of 2021 under balance sheet approach $60,000.
Step-by-step explanation:
* Under the balance sheet approach, the allowance for doubtful debt at the end of 2021 should be: Account receivable at the end of 2021 x estimated percentage of bad debt = 800,000 x 10% = $80,000
* Fluctuations in the Allowance for bad debt during 2021 includes:
+ Decrease by $28,000 due to bad debt written-off;
+ Increase by $3,000 due to reverse bad-debt written off
=> Net effect: Decrease by $25,000
* As Allowance for bad debt should be 80,000, we have the following equation:
Beginning balance - 25,000 + Bad debt expenses recorded at the end of 2021 = 80,000 <=> 45,000 - 25,000 + Bad debt expenses recorded at the end of 2021 = 80,000 <=> Bad debt expenses recorded at the end of 2021 = $60,000.
So, the bad debt expenses at the end of 2021 is $60,000.
