Exact Change

You always need to have in your pocket exact change to survive daily life. What exact change? you ask, I'll tell you. 3 quarters (because 4 would make a dollar) 2 dimes and 1 nickel ( only 2 to make .20 cause 3 would make .30, and you already have .30 with 1 quarter and the nickel; and only 1 nickel cause 2 would make .10 and you already have that) and finally 4 cents. Yes that is the perfect change. But you say that .25 repeats itself? Well of course, you can break a quarter literally to smaller pieces to make less change. That's why it repeats itself.

This is the infallible advise given to me by the librarian in charge during the shift of 10pm to midnight. Yes fun times ahead for me...
