What part exactly am I doing wrong that's making Teresa and Lisa's entries confusing to me? I understand that both customers have been issued return allowances, and I thought I was computing correctly by following the steps listed in the transactions. Yet, I've tried many variations of calculating and still coming up wrong. For example, in the schedule for accounts receivable I added up each customer's Initial purchase+sales tax, and specifically for Teresa and Lisa, I deducted their permitted allowance+sales tax to have a final answer. Is that not the right way to do it?
