OK but that is not the only answer, you could have30 quarters, 20 dimes nickles and 5 penies also.
Oops, taht was supposed to say 9 nickles.
Actually the suggestion the person before made would exceed 55 coins. I think the only option is the one supplied as the answer.
That is the only solution only if you assume have at least one of each coin type mentioned and no other coin types.
two other solutions (of at least five):
3 nickels, 21 dimes, 31 quarters.
5 pennies, 6 nickels, 14 dimes, 29 quarters, and 1 dollar coin.
