For example, how will a cut in price of V3 Motorola hand - phone affect the quantities of these items that people buying?

Second, Dell needs to decide how to produce the computers: in one location or in different locations; equipment and technologies to use; make or purchase choices, etc.
What may determine Dell's production decision: consumer demand; technological feasibility; costs of production; products of other computer producers? and so on
Third, Dell needs to decide...
