150x.43=64.5 mL
\n" ); document.write( "p+q=150
\n" ); document.write( ".13p+.58q=64.5
\n" ); document.write( "13p+58q=6450
\n" ); document.write( "13p+13q=1950
\n" ); document.write( "45q=4500
\n" ); document.write( "q=100
\n" ); document.write( "p=50
\n" ); document.write( "The chemist needs 50 mL of 13% solution and 100 mL of 58% solution..
\n" ); document.write( "
\n" );
