multiple choice question\nthe challenge businesses face when estimating the allowance for previously recorded sales is that \no at the time of the sale, it is not known which particular customer will be a \bad\ customer\no in bad economic times, fewer customers will have problems with their payments\no past default rates are not a good predictor of future default rates
Answer
Brief Explanations:
When estimating the allowance for previously - recorded sales, businesses struggle because at the time of sale, it's impossible to know which specific customer will default (be a "bad" customer). In bad economic times, more customers usually have payment problems, not fewer. While past default rates may have limitations, the main immediate challenge is the uncertainty about individual customers at the time of sale.
Answer:
A. at the time of the sale, it is not known which particular customer will be a "bad" customer
