Now we need the smallest number of notes and coins to make up this total.

I'm going to assume we're using a kind of dollars that has a $5 dollar bill in it (there being several countries whose money is called "Dollar", this needs to be stated). And so we have that, which means we have to now find currency for the remaining:

That remaining dollar can be handled with another dollar bill (US and possibly others) or dollar coin (Canada and possibly others):

Now we get into something a bit trickier - how to find the least number of coins to handle the 32 cents. We could use a quarter, a nickel, and 2 pennies (4 coins) or we could use 3 dimes and 2 pennies (5 coins). Looks like the quarter, nickel, and 2 pennies wins.

And so we end up with a $5 bill, a$1 bill/coin, a quarter, a nickel, and 2 pennies = 6 units of currency.
