I am trying to write a formula which will give me the whole sale cost working backwards from the retail price given the % mark up required. For example an iten reatiling for $6.00 need to wholesale at $3.16 at a 90% markup. I have writen a siple formula which divides the reail cost by 1.9 which gives me the right answer, What I need is a formula where I can vary the %.
