Answer:
$1,770,000
Step-by-step explanation:
The computation of the accounts receivables before the allowance is shown below;
= Beginning account receivable balance + Bad debt expense - Uncollectible accounts receivables
= $1,620,000 + $270,000 - $120,000
= $1,770,000
Bad debt is an expense hence would be added, whereas the account receivable which is not yet collected should be deducted in the computation part.
