Dave, thanks for the excellent, simple equation for the 17b solver! "No programming required," as they say.

You'll actually find this formula built in to the 17B series already, under "BUS", "MU%P" (markup as percent of price). But that's the underlying formula, useful for inclusion in larger equations that calculate commission or other things.
