You can put this solution on YOUR website!
The amount of A in the mixture is
\n" ); document.write( " $\"+.54%2A47+=+25.38+\"$ kg
\n" ); document.write( "The amount of B is $\"+47+-+25.38+=+21.62+\"$
\n" ); document.write( "------------
\n" ); document.write( "Let $\"+b+\"$ = the kg of B to be added
\n" ); document.write( " $\"+%28+21.62+%2B+b+%29+%2F+47+=+.5+\"$
\n" ); document.write( " $\"+21.62+%2B+b+=+.5%2A47+\"$
\n" ); document.write( " $\"+b+=+23.5+-+21.62+\"$
\n" ); document.write( " $\"+b+=+1.88+\"$
\n" ); document.write( "1.88 kg of B needs to be added\r
