a. complete the table below to calculate the estimated balance of allowance for doubtful accounts using…

Explanation:

Step1: Calculate estimated uncollectible for each category

For each row in the table, multiply the Accounts Receivable amount by the Percent Uncollectible (%) to get the Estimated Uncollectible amount. For example, if Accounts Receivable for "Not due" is $A$ and Percent Uncollectible is $p%$, then Estimated Uncollectible = $A\times\frac{p}{100}$. Do this for all rows: 1 - 30 days, 31 - 60 days, 61 - 90 days, and Over 90 days.

Step2: Sum up estimated uncollectible amounts

Add up the Estimated Uncollectible amounts from all the categories to find the Estimated balance of allowance for uncollectibles. Let the amounts for each category be $x_1,x_2,x_3,x_4,x_5$. Then the Estimated balance of allowance for uncollectibles = $x_1 + x_2+x_3+x_4+x_5$.

Step3: Prepare adjusting entry for credit unadjusted balance

If the unadjusted balance in Allowance for Doubtful Accounts is a $4100$ credit and the estimated balance of allowance for uncollectibles from Step 2 is $E$, the bad - debts expense amount for the adjusting entry is $E - 4100$ (if $E>4100$) or $4100 - E$ (if $E < 4100$). The adjusting entry is: Debit: Bad Debts Expense Credit: Allowance for Doubtful Accounts

Step4: Prepare adjusting entry for debit unadjusted balance

If the unadjusted balance in Allowance for Doubtful Accounts is a $600$ debit and the estimated balance of allowance for uncollectibles from Step 2 is $E$, the bad - debts expense amount for the adjusting entry is $E+600$. The adjusting entry is: Debit: Bad Debts Expense Credit: Allowance for Doubtful Accounts

Since the actual Accounts Receivable and Percent Uncollectible values are not given in the problem statement, we can't provide numerical answers. But the steps for solving are as above.

Answer:

a. Fill in the table by multiplying Accounts Receivable by Percent Uncollectible for each category and sum up the results for the final estimated balance of allowance for uncollectibles. b. Debit Bad Debts Expense and Credit Allowance for Doubtful Accounts with the calculated amount (Estimated balance of allowance for uncollectibles - 4100). c. Debit Bad Debts Expense and Credit Allowance for Doubtful Accounts with the calculated amount (Estimated balance of allowance for uncollectibles + 600).
