\r\n" );
document.write( "Let Principal be 100\r\n" );
document.write( "Amount (FV) = 200\r\n" );
document.write( "interest rate per year = 6% = 0.06\r\n" );
document.write( "compounded daily\r\n" );
document.write( "\r\n" );
document.write( "Amount = \"P%2A%281%2B0.06%2F365%29%5En\",  where 'n' is the number of days\r\n" );
document.write( "                                  (counting 365 days in a year)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "200 = 100*(1+0.06/365)^n}}}\r\n" );
document.write( "\r\n" );
document.write( "2 = \"%281+%2B+0.06%2F365%29%5En\"\r\n" );

document.write( "n = \"ln%282%29%2Fln%281%2B0.06%2F365%29%29\" = 4217 days  (rounded),  or 11.553 years  (rounded).    ANSWER\r\n" );
