elson wants to use a few pieces of silver to make a bracelet.
\n" ); document.write( " Some of the jewelry is 70% silver, and the rest is 58% silver.
\n" ); document.write( " Nelson needs 26.00g of 65% silver. How much of each alloy should he use?
\n" ); document.write( ";
\n" ); document.write( "Let x = amt of 70% silver
\n" ); document.write( "the total amt is to be 26 gr, therefore:
\n" ); document.write( "(26-x) amt of 58% silver
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation
\n" ); document.write( ":
\n" ); document.write( ".70x + .58(26-x) = .65(26)
\n" ); document.write( ".70x + 15.08 - .58x = 16.9
\n" ); document.write( ".70x - .58x = 16.9 - 15.08
\n" ); document.write( ".12x = 1.82
\n" ); document.write( "x = 1.82/.12
\n" ); document.write( "x = 15\"1%2F6\" gr of 70% silver
\n" ); document.write( "and
\n" ); document.write( "26 - 15\"1%2F6\" = 10\"5%2F6\" gr of 58% silver
\n" ); document.write( "
\n" );
