That's easy:
Create an CartRepository that knows about AR and let it have a
DeleteItem(CartItem item) method.
If you are purist, create ICartRepository in the domain layer and
ARCartRepository in the persistance layer, and match them with IoC.
ICartRepository then defines DeleteItem(CartItem item) and ARCartRepository
implements it. This allows you to create MockCartRepository for testing etc.
