\r\n" );
document.write( "Let X be the original cost, \"e\" be the equivalent discount for these three \r\n" );
document.write( "successive discounts, as a decimal value.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then \r\n" );

document.write( "\r\n" );
document.write( "Cancel X in both sides.  You will get\r\n" );
document.write( "\r\n" );
document.write( "    1 - e = 0.95*0.92*0.76 = 0.66424,\r\n" );

document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The equivalent discount is 0.33576,  or  33.576%.    ANSWER\r\n" );
