Let $\"+c+\"$ = price per pound of copper in dollars
\n" ); document.write( "Let $\"+t+=+c+%2B+2+\"$ = price per pound of tin in dollars
\n" ); document.write( "given:
\n" ); document.write( " $\"+2t+%2B+8c+=+3.65%2A10+\"$
\n" ); document.write( " $\"+2%2A%28+c+%2B+2+%29+%2B+8c+=+3.65%2A10+\"$
\n" ); document.write( " $\"+2c+%2B+4+%2B+8c+=+3.65%2A10+\"$
\n" ); document.write( " $\"+10c+=+36.5+-+4+\"$
\n" ); document.write( " $\"+10c+=+32.5+\"$
\n" ); document.write( " $\"+c+=+3.25+\"$
\n" ); document.write( "and
