percent ---------------- quantity
\n" ); document.write( "Alloy type I 80 ---------------- 500 ounce
\n" ); document.write( "Alloy type II 40 ---------------- x ounce
\n" ); document.write( "Mixture 60 ---------------- 500 + x ounce
\n" ); document.write( "
\n" ); document.write( "80*500+40x=60(500+x)
\n" ); document.write( "40000+40x=30000+60x
\n" ); document.write( "40x-60 x= 30000 -40000
\n" ); document.write( "-20 x = -10000
\n" ); document.write( "/ -20
\n" ); document.write( "x= 500 ounce of Alloy type II
\n" ); document.write( "
