Devi und Dave hatten anfangs den gleichen Geldbetrag x. Nachdem Devi 258 Dollar und Dave 196 Dollar für wohltätige Zwecke gespendet hatte, hatte Dave dreimal so viel wie Devi. Wie viel hatte Dave am Ende?
Hello Guest!
\(x-258+x-196=x-258+3(x-258)\)
Devi Dave Devi Dave
\(2x-454=x-258+3x-774\\ -2x=-578 \)
\(x=289\)
Dave ended up with $289 - $196 = $ 93
