Answer:
$19,100
Explanation:
Accounts receivable represents amount owed to a business by its customers for products or services offered. It is payable in the future.
When collection is uncertain the amount is put in doubtful account.
If an amount is confirmed to be uncollectible it is written off as a loss
In this scenario we are calculating realisable value after write-off
Account receivable after write-off = Account receivable balance - Uncollectible amount
Account receivable after write-off= 21,000 - 530= $20,470
Allowance balance after write-off= Doubtful account - Uncollectible account
Allowance balance after write-off= 1,900 - 530 = $1,370
Net realisable value after write-off= 20,470 - 1,370= $19,100
