Young and Old Corporation $($YOC$)$ uses two aging categories to estimate uncollectible accounts. Accounts less than $60$ days are considered young and have a $5\%$ uncollectible rate. Accounts more than $60$ days are considered old and have a $40\%$ uncollectible rate.

Required:

If YOC has $$100,000$ of young accounts and $$400,000$ of old accounts, how much should be reported in the Allowance for Doubtful Accounts?

If YOC$$s Allowance for Doubtful Accounts currently has an unadjusted credit balance of $$40,000,$ how much should be credited to the account?

If YOC$$s Allowance for Doubtful Accounts has an unadjusted debit balance of $$5,000,$ how much should be credited to the account?
