Colwell Corporation operates in an industry that has a high rate of bad debts. On 12/31/20 before any year-end adjustments, the balance in Colwell's Accounts Receivable account was $915,000 and the Allowance for Doubtful Accounts had a credit balance of $5,000. Colwell assumes that 5% of receivables will ultimately become uncollectible.

1. Before making its year end adjustment, Colwell determines that an account of $7,000 is uncollectible and decides to write off the account. What entry will Colwell make to write it off?
2. Assuming that Colwell then uses the percentage of receivables to apply the allowance method, what is the appropriate ending balance for the Allowance for Doubtful Accounts on 12/31/20?
3. What adjusting entry will Colwell make at 12/31/20?
4. Show how accounts receivable would be presented on the 12/31/20 balance sheet

Please show all work. Trying to understand this, thank you!
