Textaufgabe

Hallo Anonymous,

die Zinsformel heißt     $${\mathtt{Z}} = {\frac{{\mathtt{K}}{\mathtt{\,\times\,}}{i}{\mathtt{\,\times\,}}{\mathtt{p}}}{{\mathtt{100}}}}$$           =>     $${\mathtt{p}} = {\frac{{\mathtt{z}}{\mathtt{\,\times\,}}{\mathtt{100}}}{\left({\mathtt{K}}{\mathtt{\,\times\,}}{i}\right)}}$$

$${\mathtt{p}} = {\frac{{\mathtt{416.32}}{\mathtt{\,\times\,}}{\mathtt{100}}}{\left({\mathtt{4\,000}}{\mathtt{\,\times\,}}{\mathtt{5}}\right)}} \Rightarrow {\mathtt{p}} = {\mathtt{2.081\: \!6}}$$

Du liegst mit deinen  2  %  also richtig   ( p = 2,08 %)
