How many mL's of a 10% alcohol solution and how many mL's of a 20% solution must be mixed to obtain 30 mL's of a 16% solution?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of 20% solution
\n" ); document.write( "total is be 30 ml, therefore
\n" ); document.write( "(30-x) = amt of 10%
\n" ); document.write( ":
\n" ); document.write( "Solve this simple mixture equation
\n" ); document.write( ".10(30-x) + .20x = .16(30) \n" ); document.write( "

\n" );
