Williamson Distributors separates its accounts receivable into three age groups for purposes of estimating the percentage of uncollectible accounts.

Accounts not yet due = $20,000; estimated uncollectible = 5%.

Accounts 130 days past due = $9,000; estimated uncollectible = 20%.

Accounts more than 30 days past due = $3,000; estimated uncollectible = 30%.

Compute the total estimated uncollectible accounts.
