Final answer:
The last segmentation variable to consider is income. Sauber should target consumers with medium incomes (between $40,000 and $99,999).
Step-by-step explanation:
The last segmentation variable to consider is income. Sauber should target consumers with medium incomes (between $40,000 and $99,999). They should not target consumers with high incomes (greater than $100,000) because those consumers are less likely to let price increases affect their purchasing decisions. Sauber eliminated consumers with incomes less than $40,000 from consideration because they do not have the ability to purchase their own laundry machines.
