Our first GUEST made the classic mistake of percentages in that the percentage changes as to whether you are going up or down. ie a 50% markup means you have a 33% gross profit. Sorry, Nate, you made that mistake in your first post, as well, so I won't be sending you any takers on math homework.

BUT, McGrath and GUEST Nigel mentioned something I have always been curious about. Just how did shillings, farthings etc work? How many x in y? I have always wanted to know...

And, Mrrzy, I think you're better off to stick with your old choice which had a 2/3 chance of correctness, rather than changing to the new choice which only has a 1/2 chance, or has your first choice changed to a 1/3 chance now that there is an ass revealed? I woke up with a ringing headache this morning and had to sing the song I wrote to Alex'(the Mousethief) words, at the local HS. I managed that (best I've ever done) but my head still isn'quite up to probabilities. But I have to do the tax stuff all the time...
