I looked up "add up" in the Cambridge Dictionary and I saw these two examples:
If you buy three packets, it adds up to a total of $18.
Cinema tickets, drinks, snacks - it all adds up to a lot a money.
Can someone tell me why IT is used but not THEY in both examples? Shouldn't THEY be used to refer to the "three packets" or "tickets, drinks, snacks"?
