Question 709813
<pre>
Besides his quarters he has but 50 cents, so he has
to use at least one quarter.
 
If he uses 1 quarter, he has 40 cent left to make.
He can do that in two ways, by using 2 dimes and
all four nickels, or all 3 dimes snd 2 nickels.
That's 2 ways.

If he uses both quarters, he has 15 cent left to make.
He can do that in two ways by using 1 dime and 1 nickel,
or no dimes and 3 nickels.
That's 2 more ways.
    
So there are four ways to make 65 cents.
