--------percent ---------------- quantity
\n" ); document.write( "soda 0 ---------------- 3 quarts
\n" ); document.write( "fruit juice 45 ---------------- x quarts
\n" ); document.write( "Mixture 30 ---------------- 3 + x quarts
\n" ); document.write( "
\n" ); document.write( "0 * 3 + 45 x = 30 ( 3 + x )
\n" ); document.write( "0 + 45 x = 90 + 30 x
\n" ); document.write( "45 x + -30 x = 90 - 0
\n" ); document.write( "15 x = 90
\n" ); document.write( "/ 15
\n" ); document.write( "x = 6
\n" ); document.write( " 6 quarts of 45 % fruit juice
\n" ); document.write( "
