A customer searching for an SUV is trying to decide what to buy. She decides to limit her options by using the following strategy. First, the car must be a Honda or a Toyota because the customer believes that they have the highest quality. Second, the vehicle cannot cost more than $30,000 or get less than 10 miles per gallon. Third, the remaining vehicles' interiors, comfort, and instrument placing will be judged by giving each a score and summing them. The SUVs that are left, with the highest summed scores, will be selected for an intensive test drive. What type of decision rules was this customer proposing to use? There will be more than one rule used.
