Ok - my job doesn't centre around maths this is a one off. Just go spout your holier than thou {censored} elsewhere. I had a choice - come here and get an answer in 5 minutes whilst doing other work or sit down ignoring my clients and working it out. I took the lazy option. Thank you to everyone else for explaining. No need to be so hostile, he was trying to help.

Well I did A level maths... I've just totally forgotton it and had a mind blank!! We've gotta work out costs for something but only have the final figure... I don't really get your formula either, please explain 5000 divided by 1.25 = 4000
