１９、The following appeared in a memo from the new vice president of Sartorian, a company that manufactures men’s clothing. "Five years ago, at a time when we had difficulties in obtaining reliable supplies of high-quality wool fabric, we discontinued production of our deluxe alpaca overcoats. Now that we have a new fabric supplier, we should resume production. This coat should sell very well: since we have not offered an alpaca overcoat for five years and since our major competitor no longer makes an alpaca overcoat, there will be pent-up customer demand. Also, since the price of most types of clothing has risen in each of the past five years, customers should be willing to pay significantly higher prices for alpaca overcoats than they did five years ago, and our company profits will increase."
