Hello Guest!

 

Wie viele Gallonen einer 20%igen Alkohollösung sollten zu 40 Gallonen einer 50%igen Alkohollösung hinzugefügt werden, um eine 30%ige Lösung herzustellen?

 

\(40gal\cdot0.5+x\cdot0.2=(x+40gal)\cdot0.3\\ 20gal+0.2x=0.3x+12gal\ |\ -0.2x-12gal\\ 8gal=0.1x\ |\ /0.1\)

\(80gal=x\)

 

80 gallons of 20% solution must be added to the 40 gallons of 50% solution.
