Answer:
1) effective interest rate (for the 9 months period)= (1 + 10%/12)⁹ - 1 = 1.07754 -1 = 0.07754 = 7.75%
2) accrued interest = ($15,545/9) x 2 = $3,454.44 = $3,454
December 31, 2016, accrued interest on non-interest bearing note
Dr Discount on notes receivable 3,454
Cr Interest revenue 3,454
3) July 31, 2017, collection of non-interest bearing note receivable
Dr Cash 216,000
Dr Discount on notes receivable 12,091
Cr Notes receivable 216,000
Cr Interest revenue 12,091
4) November 1, 2016, non-interest bearing note receivable issued [I will assume that the note receivable was made for a sales operation (if it was made for a loan, you can just change sales revenue for cash)]
Dr Notes receivable 216,000
Cr Sales revenue / cash 200,455
Cr Discount on notes receivable 15,545
Explanation:
we have to first calculate the present value of the note using the 10% discount rate:
PV = $216,000 / (1 + 10%/12)⁹ = $216,000 / (1 + 0.8333%)⁹ = $200,454.88 = $200,455
