A goldsmith mixed 10 g of a 60% gold alloy with 40 g of a 25% gold alloy.
\n" ); document.write( " What is the percent concentration of the resulting alloy?
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation, the total result will be 10+40 = 50 mg
\n" ); document.write( "let x = the decimal form of resulting percent
\n" ); document.write( ":
\n" ); document.write( ".60(10) + .25(40) = 50x
\n" ); document.write( "6 + 10 = 50x
\n" ); document.write( "16 = 50x
\n" ); document.write( "16/50 = x
\n" ); document.write( "x = .32, result is 32% gold alloy
\n" ); document.write( "
\n" );
