Algebra.Com's Answer #338174 by chessace(471)![]() ![]() You can put this solution on YOUR website! 50% concentration is the desired answer. \n" ); document.write( "You computed x = # quarts (out of 4 total) of OJ in the final. \n" ); document.write( "Actually, your \"x\" changed meaning in midstream. \n" ); document.write( "Better continuation of what you wrote: \n" ); document.write( "2*1 + 2*0 = x quantity * y concentration \n" ); document.write( "x = 2+2 (the total volume) \n" ); document.write( "2 = 4 y \n" ); document.write( "y = 1/2 concentration. \n" ); document.write( " \n" ); document.write( " |
