Final answer:
The bad debts expense for 2013 is $522,000.
Step-by-step explanation:
The bad debts expense for 2013 can be calculated by considering the sales on account, collections on account, write-offs, and the estimated uncollectible accounts. The calculation is as follows:
- Add the sales on account to the beginning balance of accounts receivable: $525,000 + $145,000 = $670,000.
- Subtract the collections on account: $670,000 - $100,000 = $570,000.
- Add the write-offs: $570,000 - $8,000 = $562,000.
- Subtract the estimated uncollectible accounts: $562,000 - $40,000 = $522,000.
Therefore, the bad debts expense for 2013 is $522,000.
