\section*{Taux d'évolution réciproque}
\begin{propriete}
Quand une quantité subit une évolution et que l'on souhaite revenir à la valeur initiale, elle subit une \textbf{évolution réciproque}.

Le coefficient multiplicateur de l'évolution réciproque est égal à $\dfrac{1}{CM}$.
Le taux d'évolution réciproque est égal à $\dfrac{1}{CM} - 1$

\paragraph{Exemples:}
\begin{itemize}
\item Un article coûte 50\euro hors taxe. Une diminution de 20\% fait passer le prix à 40\euro. Quelle devra être l'augmentation pour revenir au prix initial?
\vspace{1cm}
\item Une entreprise a augmenté ses emissions de CO2 de 14\% en un an. Quelle devra être l'évolution pour revenir aux émissions d'avant cette augmentation?
