14. Based on the ending balance of accounts receivable, assume that 5% will be written off in the coming year and update the allowance account to reflect this amount.

I am going to attach the first half of the question below, however, I only need help with 6-14.

Accounts Receivable, Notes Receivable

Beginning Balance in Accounts Receivable: $15,000

Beginning Balance in Allowance for Uncollectible Accounts is a debit of $120

You will need to prepare a t-account for accounts receivable and allowance for uncollectible (doubtful) accounts. Use a 360-day year to calculate interest.

1. Adjust the allowance for uncollectible accounts assuming that 10% of the balance accounts receivable will be written off in the coming year.
2. Derrick sends a note via carrier pigeon stating he will not be able to pay off his account. Write off the $270 account using the allowance method.
3. Archie audits Merediths accounting records for $2,000. is paid in cash and the remainder put on account.
4. Torres calls and requests an extension on her accounts receivable. Her $5,000 account is transferred to a notes receivable with terms of 10% and 90 days.
5. Cristina dishonors her note receivable of $3,000. Terms were 60 days and 5% interest. Charge back to accounts receivable.
