how many liters of a 30% solution should be added to 50 liters of a 15% solution if the final mixture should contain 20% solution?
\n" ); document.write( "------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "active + active = active
\n" ); document.write( "0.30x + 0.15*50 = 0.20(x+50)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "30x + 15*50 = 20x + 20*50
\n" ); document.write( "10x = 5*50
\n" ); document.write( "x = 25 liters (amt. of 30% solution needed in the mixture)
