Assume we have the following code:

## A simulated cash register that tracks the item count and the total amount due.

#

class CashRegister:

def$\_$init$\_($self$)$:

selfitemCount $=0$ # an integer

self.totalCost $=0$ # intended to be a floating point number

## Adds an item to this cash register.

# @param price the price of this item

#

def addItem$($self$,$ price$)$ :

self.itemCount $=$ selfitemCount $+1$

self.totalPrice $=$ self.totalPrice $+$ price

## Gets the price of all items in the current sale.

# @return the total price

#

def getTotal$($self$)$:

return self.total Cost

## Gets the number of items in the current sale.

# @return the item count

#

def getCount$($self$)$ :

return selfitemCount

## Clears the item count and the total.

#

def clear$($self$)$ :

self.itemCount $=0$

self.totalCost $=0$

a$.$ Write the comment and implementation of a 'getDollars' method that returns the amount of the total sale as a dollar value without the cents.

b$.$ Is the getDollars method above an accessor or a mutator?
