Answer:
$430,000
Step-by-step explanation:
The computation of Allowance for doubtful accounts is shown below:-
Allowance for doubtful accounts on 31 Dec 2021 = Allowance for doubtful accounts as on 1 Jan 2021 - Written off uncollectible + Bad debt expenses
= $524,000 - $634,000 + (3% × $18,000,000)
= $524,000 - $634,000 + $540,000
= $1,064,000 - $634,000
= $430,000
Therefore for computing the Allowance for doubtful accounts on 31 Dec 2021 we simply applied the above formula.
