Forty ounces of a 40% gold alloy are mixed with 60 oz of a 10% gold alloy.
\n" ); document.write( " Find the percent concentration of the resulting gold alloy.
\n" ); document.write( ":
\n" ); document.write( "let x = resulting percent in decimal form
\n" ); document.write( "mixture total: 40 + 60 = 100 oz
\n" ); document.write( ":
\n" ); document.write( "100x = .4(40) + .1(60)
\n" ); document.write( "100x = 16 + 6
\n" ); document.write( "100x = 22
\n" ); document.write( "x = \"22%2F100\"
\n" ); document.write( "x = .22 which is 22% gold concentration
\n" ); document.write( "
\n" );
