Instance variables are attributes or properties that store the state of an instance of a class. In the context of a CashRegister class, "purchase" is likely to be an instance variable because it represents the total amount of purchases made on a particular instance of the cash register, which varies from one CashRegister object to another. Other options like amount, balance, and change could also be instance variables in different contexts, but without more information, "purchase" is the most typical example of an instance variable for tracking the state of transactions in a CashRegister class.
