If Revenue Equals (Cost Plus Profit) And Profit Margin Equals (Profit Over Revenue), Markup Equals ((1 Over (1 Minus Profit Margin)) All minus 1).
To Proove this, (multiply Cost By (1 Plus Markup)) Should Equal Revenue.

Example:
3,819.66 + 6,180.34 = 10,000
6,180.34 / 10,000 = .6180339887
(1 / (1 - .6180339887)) - 1 = 1.6180339887
3,819.66 x (1 + 1.6180339887) = 10,000
