Start: [E] => 0,00

40 [A] => 0,00
50 [B] => 0,00
     [C] => 20,00

So the margin is 20%.
Note that there was no need to enter zero as the display already was 0,00.

What if the margin is increased to 25%?

25 [C] => 0,00
     [B] => 53,33

So the price has to be raised to 53,33.

Does this work for you?

Sorry, it doesn´t work for me. I checked key stroking twice. When I press [C] in the sequence as 4th. step, I got =0, not 20. The same happens when I use HP67
