track of sales tax

`

1. Consider the data representation of a cash register that keeps track of sales tax in Section 8.8. Instead of tracking the taxable total, track the total sales tax. Redo the walkthrough with this change.

2. Suppose the Cash Register needs to support a method void undo() that undoes the addition of the preceding item. This enables a cashier to quickly undo a mistake. What instance variables should you add to the Cash Register class to support this modification?
