Mental maths

So I'm standing in an orderly line waiting to be called. I am occupying myself in constructive fashion, neither fidgeting nor prodding the people on either side of me. I am not whispering comments designed to amuse or denigrate. I am practising being clear-minded!

I am endeavouring to calculate the sum of the individual items that I have ordered. I am waiting for two things at £1.80 each. This comes from the top of the board on the left. From the bottom of this list I take £2.85. Moving across to the wider board in the middle I am concerned with one £2.00 and one £1.50.

I attempt six times to total all five things. I am ashamed to say that I came up with six different answers each time! One of them was, at least, correct. Needless to say Prince Charming got it right first time and with alacrity. (No writing down of the sum was permitted!)

Answers on a postcard, or in a comment, please!
