Wiw berechnet man den abnahmefaktor, den neuen und altwn preis und die senkung?

Hallo Anonymous,

alter Preis       AP       =>  100 %                   200 €   =>  100%

- Abnahme       A       =>    x   %                 -  50 €   => 100*50/200 = 25%  

neuer Preis      NP      =>     y   %                  150 €    => 75%                        =>  f = 0,75

y= NP*100/AP            f = NP/AP            f = 0,75

NP = AP*f                   AP = NP/f

$${\mathtt{NP}} = {\mathtt{AP}}{\mathtt{\,\times\,}}{\mathtt{f}}$$            $${\mathtt{AP}} = {\frac{{\mathtt{NP}}}{{\mathtt{f}}}}$$            $${\mathtt{A}} = {\mathtt{AP}}{\mathtt{\,-\,}}{\mathtt{NP}}$$

$${\mathtt{NP}} = {\mathtt{200}}{euro}{\mathtt{\,\times\,}}{\mathtt{0.75}} = {\mathtt{150}}{euro}$$          

  $${\mathtt{AP}} = {\frac{{\mathtt{150}}{euro}}{{\mathtt{0.75}}}} = {\mathtt{200}}{euro}$$     

$${\mathtt{A}} = {\mathtt{200}}{euro}{\mathtt{\,-\,}}{\mathtt{150}}{euro} = {\mathtt{50}}{euro}$$        

Wenn du dein Zahlenbeispiel senden würdest, könnten wir das noch einmal durchrechnen.

Schicke uns doch mal die Aufgabe.
