document.write( "Let x = # of the 20-dollar bills Philip has.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the number of 50-dollar bills is 2x, and the number of the 100-dollar bills is 2*(2x) = 4x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the total money is  20x + 50*(2x) + 100*(4x) = (20+100+400)x = 520x dollars,\r\n" );
document.write( "\r\n" );
document.write( "and it is equal to 1560 dollars, according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    520x = 1560\r\n" );
document.write( "\r\n" );
document.write( "   \r\n" );
document.write( "Hence, x = 1560/520 = 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus, there are 3 20-dollar bills,  6 50-dollar bills and 12 100-dollar bills.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In all, there are 3+6+12 = 21 bills.      ANSWER.  \r\n" );
