Number of states in LR(0)

Question

How many states are there in the following augmented grammar using lr(0) parser ?

S -> .Sdollar   (Dollar is actually symbol dollar but it's causing formatting issue so I wrote it in words)

S -> x / (A)

A -> A,S / S

In first production do we shift two times or one time ?

S -> S.dollar and S->Sdollar.  or only S->S.dollar . Because last symbol is implicit right ?

Answer 1

In first production we shift one time.

Totally 9 states
