\n" );
document.write( "Hi,
\n" );
document.write( "*Note: the cheaper brand was added to 650ml of the 50% fruit punch
\n" );
document.write( "Let x be the concentration in the punch added
\n" );
document.write( ".50*650 + x*100 = .48*750
\n" );
document.write( "Simplify and solve
\n" );
document.write( "100x = .48*750ml - .50*650ml
\n" );
document.write( "100x = 360 -325
\n" );
document.write( "100x = 35
\n" );
document.write( "x = .35
\n" );
document.write( "Concentration in the punch that Jill added was 35%
\n" );
document.write( "check your answer
\n" );
document.write( "325 + 35 = 360 \n" );
document.write( "

\n" );
