--------percent ---------------- quantity
\n" ); document.write( "Juice I 17 ---------------- 15 gallons
\n" ); document.write( "juice II 30 ---------------- x gallons
\n" ); document.write( "Mixture 20 ---------------- 15 + x gallons
\n" ); document.write( "
\n" ); document.write( "17 * 15 + 30 x = 20 ( 15 + x )
\n" ); document.write( "255 + 30 x = 300 + 20 x
\n" ); document.write( "30 x + -20 x = 300 - -255
\n" ); document.write( "10 x = 45
\n" ); document.write( "/ 10
\n" ); document.write( "x = 4.5
\n" ); document.write( " 4.5 gallons of 30 % juice II
