Infotek, a computer manufacturer in Katrovia, has just introduced a new personal computer model that sells for significantly less than any other model  Market research shows, however, that very few Katrovian households without personal computers would buy a computer, regardless of its price
Ttherefore, introducing the new model is unlikely to increase the number of computers in Katrovian homes
Katrovians in households that already have computers are unlikely to purchase the new Infotek model as an additional computer for home use.
