Ann: Let's see I had the salmon starter which was £5.90 and my Pizza was £8.25.
Jane: I had the soup and bruchetta which all together is £4.50 and my trout for the main course was £12.
Ann: So that's £14.15 for me and £16.50 for you.
Jane: Yes and shall we go fifty-fifty for the wine?
Ann: Yes, so that's an extra £6 for both of us.
Jane: So now your bill comes to £20.15 and I need to pay £22.50.
Ann: And I had a dessert - that's another £3.50. And you had coffee which is £2.
Jane: And is that all?
Ann: Yes, this is everything on the list.
Jane: So now my bill is £24.50 and yours come to £23.65. Is that correct?
Ann: Yes, that's exactly it. How much tip shall we give the waiter?
Jane: I think £5 would be good.
