percent percentage ---------------- quantity
\n" ); document.write( "antifreeze I 65 ---------------- x gal
\n" ); document.write( "antifreeze II 35 ---------------- 15 - x gal
\n" ); document.write( "Mixture 53.00% ---------------- 15
\n" ); document.write( "
\n" ); document.write( "65 x + 35 ( 15 - x ) = 53 * 15
\n" ); document.write( "
\n" ); document.write( "65 x + 525 - 35 x = 795
\n" ); document.write( "65 x - 35 x = 795 - 525
\n" ); document.write( "30 x = 270
\n" ); document.write( "/ 30
\n" ); document.write( " x= 9 gal 65.00% antifreeze I
\n" ); document.write( " 6 gal 35.00% antifreeze II
\n" ); document.write( "
