i'm a bit confused..could u help me?
i'm at the cimena, i have just bought two tickets..the ticket seller gives them to me and says 'that's £ 20'
i was wondering if it is possible to say ' it's £ 20' instead of that's
they're (the tickets are) £20
how much are those shoes? they're £40
how much is that dress? It's £ 30
thanks in advance
