You can put this solution on YOUR website!
(30%)(100) + (10%)(x) = (15%)(100 + x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3000 + 10x = 1500 + 15x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1500 = 5x ___ 300 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "300 lb of 10% along with 100 lb of 30% makes 400 lb of 15%
\n" ); document.write( "
\n" );
