Assume you own a computer retail store located near your campus (give the store any name you want). You have sold fewer PCs in recent years due to strong demand for macs among university students. You will write a sales letter to reach all student housing units. Your goal is to encourage students to purchase PCs at your store. You can do online research to help you contrast PCs with macs and identify price levels. In the sales letter, attempt to show students the advantages of PCs compared to macs and get them to take specific steps to learn more about or even purchase a PC at your store.
