Blain Company has $10,000 of accounts receivable that are current, $5,000 that are between 0 and 30 days past due, $3,000 that are between 30 and 60 days past due, and $800 that are more than 60 days past due. Bain estimates that 2% of the receivables that are current will be uncollectible, 5% of those between 0 and 30 days past due will be uncollectible, 10% of those between 30 and 60 days past due will be uncollectible, and 50% of those more than 60 days past due will be uncollectible. Just prior to recognizing uncollectible accounts expense, Blain's allowance for doubtful accounts account has a $100 positive balance. Assuming Blain uses the aging method to estimate uncollectible accounts expense, the amount of uncollectible expense will be

a. $1,300.
b. $1150
c. $900.
d. $1050.
