At the end of the current year, the accounts receivable account has a debit balance of $$2,055,000$ and sales for the year total $$28,770,000.$ Determine the amount of the adjusting entry to provide for doubtful accounts under each of the following assumptions:

a$.$ The allowance account before adjustment has a debit balance of $$14,000.$ Bad debt expense is estimated at $\frac{1}{2}$ of $1\%$ of sales.

b$.$ The allowance account before adjustment has a debit balance of $$14,000.$ An aging of the accounts in the customer ledger indicates estimated doubtful accounts of $$30,030.$

c$.$ The allowance account before adjustment has a credit balance of $$7,800.$ Bad debt expense is estimated at $\frac{1}{4}$ of $1\%$ of sales.

d$.$ The allowance account before adjustment has a credit balance of $$7,800.$ An aging of the accounts in the customer ledger indicates estimated doubtful accounts of $$64,700.$
