There are four types of coins, pennies ($0.01), nickels ($0.05) dimes ($0.10) and quarters ($0.25). Peggy's piggy bank contains 49 coins. Is there at least one of each type of coin in her piggy bank?

(1) There is $1.00 in the piggy bank. (2) The ratio of the number of dimes to the number of pennies is 3:20. Last edited by kevincan on 29 Sep 2006, 16:39, edited 1 time in total.

What about 1x25c + 45x1c + 3x10c ? I guess that doesn't change answer 'NO', since nickles are missing. but this really seems to be time consuming problem! Is there a good solution? here is a solution to a similar problem: http://mathforum.org/library/drmath/view/57987.html Re: DS: Peggy's Piggy Bank [#permalink] 29 Sep 2006, 16:31 Similar topics Replies Last post Similar Topics: 2 In a piggy bank filled with only pennies, nickels, and dimes, what is 2 07 Oct 2014, 08:09 10 Billy has an unlimited supply of the following coins: pennie 12 24 Oct 2011, 22:19 Penny Nickel Dime 2 12 May 2011, 00:04 A hand purse contains 6 nickels, 5 pennies and 4 dimes.
