document.write( "You obviously can't have any pennies, because you couldn't have 1-4 pennies,\r\n" );
document.write( "since $1.15 is a multiple of 5, and if you had 5 pennies or more you could\r\n" );
document.write( "change a nickel. \r\n" );
document.write( "\r\n" );
document.write( "You can't have more than 1 nickel, otherwise you could change a dime.\r\n" );
document.write( "And if you had 1 nickel you couldn't have but 1 dime, otherwise you could\r\n" );
document.write( "change a quarter.  Then if you had 1 nickel and 1 dime you'd have 15 cents.\r\n" );

document.write( "dimes and halves only, so you must have at least 1 quarter.  You can't have\r\n" );
document.write( "more that one quarter, otherwise you could change a half. So you must have\r\n" );
document.write( "exactly 1 quarter. \r\n" );
document.write( "\r\n" );
document.write( "That leaves 90 cents, to make with a half dollar and dimes.  So that's 1\r\n" );
document.write( "half and 4 dimes. And with only 4 dimes you can't change a half dollar.\r\n" );
document.write( "\r\n" );
document.write( "So that's the answer:  4 dimes, a quarter and a half dollar.    \r\n" );
