a sugar solution was made by mixing 1 qt. of a 89% sugar solution and 12 qt. of a 50% sugar solution. what is the concentration of the mixture?
\n" ); document.write( "**
\n" ); document.write( "let x=concentration of mixture
\n" ); document.write( "89%*1+50%*12=x*13
\n" ); document.write( ".89+6=13x
\n" ); document.write( "6.89=13x
\n" ); document.write( "x=6.89/13=.53
\n" ); document.write( "concentration of mixture=53% \n" ); document.write( "

\n" );
