\n" ); document.write( "Given a chain discount of \"15%2F12\" what will the single equivalent discount rate be?
\n" ); document.write( "
\n" ); document.write( "\"15%2F12\" means a customer might be offered \"15\"% off the list price of a particular product and then a further \"12\"% for purchasing in volume\r
\n" ); document.write( "\n" ); document.write( "Single equivalent discount = Chain Discounts / List Price\r
\n" ); document.write( "\n" ); document.write( "In general the single equivalent rate can be calculated using the SED formula which can be stated as follows:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"SED+=+1+-+%281-15%29\"% * \"%281-12%29\"%\r
\n" ); document.write( "\n" ); document.write( "\"SED+=+1+-+%281-0.15%29+%2A+%281-0.12%29+\"\r
\n" ); document.write( "\n" ); document.write( "\"SED+=+1+-+%280.85%29+%2A+%280.88%29+\"\r
\n" ); document.write( "\n" ); document.write( "\"SED+=+1+-+0.748\"
\n" ); document.write( "
\n" ); document.write( "\"SED+=+0.252\" -> the single equivalent discount rate (\"25.2\"%)\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
