As you might have guessed, margin and rate of markup are not the same thing. Margin is determined from selling price and markup is determined from cost. But this doesn't mean you can't convert between the two.
selling price = cost / (1-margin)
selling price = cost * (1 + rate of markup).
So if we set these two equations equal
cost
---------- = cost (1 + rate of markup)
1-margin
Divide both sides by cost and plug in .49 for margin and you get:
1/(1-.49)=1 + rate of markup
1.96=1 + rate of markup
so rate of markup is .96
Hope that helps!
