**Reiny**, Wednesday, September 15, 2010 at 10:58pmThe only possible cases are, hope I did not miss any

DDD - 30

DDN - 25

DDQ - 45

DNN - 20

DNQ - 40

DQQ - 60

NNN - 15

NNQ - 35

NQQ - 55

How many of these amount to at least 25 cents?

(notice that the fact that we have 5 dimes and 4 nickels is of no consequence, since we can use at most 3, but the 2 quarters limits the cases)
