Marydale Products permits its customers to defer payment by giving personal notes instead of cash. All the notes bear interest and require the customer to pay the entire note in a single payment 6 months after issuance. Consider the following transactions, which describe Marydale's experience with two such notes:
a. On October 31, 2019, Marydale accepts a 6-month, 9% note from Customer A in lieu of a $3,600 cash payment for services provided that day.
