A mixture of 10% acid and 90% water is added to 5 liters of pure acid.
\n" ); document.write( " The final mixture is 40% water.
\n" ); document.write( " How many liters of water are in the final mixture?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of acid/water mixture added
\n" ); document.write( ";
\n" ); document.write( "Write an amt of water equation
\n" ); document.write( ".90x = .40(x + 5)
\n" ); document.write( ".90x = .40x + 2
\n" ); document.write( ".9x - .4x = 2
\n" ); document.write( ".5x = 2
\n" ); document.write( "x = \"2%2F.5\"
\n" ); document.write( "x = 4 liters of 90% water mixture added to the 5 liters of pure acid
\n" ); document.write( ":
\n" ); document.write( "Find the amt of water in the final mixture
\n" ); document.write( "w = .4(4+5)
\n" ); document.write( "w = .4(9)
\n" ); document.write( "w = 3.6 liters is water in the final mixture
\n" ); document.write( " \n" ); document.write( "
\n" );
