Final answer:
When an account is written off using the allowance method, the allowance account will increase, the cash realizable value of total accounts receivable will stay the same, and the net accounts receivable will decrease.
Step-by-step explanation:
When an account is written off using the allowance method, the allowance account will increase. This is because the allowance account represents the estimated amount for uncollectible accounts, and when an account is written off, it means that it is considered uncollectible.
The cash realizable value of total accounts receivable will stay the same, as the account that is being written off is already considered uncollectible and not included in the cash realizable value.
However, the net accounts receivable will decrease. Net accounts receivable is calculated by subtracting the allowance for doubtful accounts from the total accounts receivable. When an account is written off, the allowance for doubtful accounts increases, resulting in a decrease in net accounts receivable.
