40g alloy containing 35% gold to be melted with 20g alloy containing 50% gold.
\n" ); document.write( " how much % of gold resulting from alloy??
\n" ); document.write( ";
\n" ); document.write( "Let x = resulting per cent of gold in decimal form
\n" ); document.write( ":
\n" ); document.write( "Write an amt of gold equation:
\n" ); document.write( ":
\n" ); document.write( ".35(40) + .50(20) = x(40+20)
\n" ); document.write( "14 + 10 = 60x
\n" ); document.write( "24 = 60x
\n" ); document.write( "x = \"24%2F60\"
\n" ); document.write( "x = .4 * 100 = 40% gold is the results
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this using the amt of gold equation
\n" ); document.write( ".35(40) + .50(20) = .40(40+20)
\n" ); document.write( " 14 + 10 = 24
\n" ); document.write( "
\n" );
