Well, isn't that a happy little math problem we have here! If Ann has more 50c coins than 10c coins and the total value is $5, we can figure out that she must have 4 10c coins. Let's give Ann a little encouragement as she counts her coins and solves this puzzle.
a quarter and a dime (25c+10c=35c)
10 x 10c coins
Indeed. 74 cents can be made with the following set of 7 coins: 50c 10c 10c 1c 1c 1c 1c
20c x 7, plus 10c x 1 20c x 6, plus 10c x 3 20c x 5, plus 10c x 5 20c x 4, plus 10c x 7 20c x 3, plus 10c x 9 20c x 2, plus 10c x 11 20c x 1, plus 10c x 13
10
Half of one.

Nine American coins to sum up to 93 cents: 25c 25c 25c 10c 10c 5c 1c 1c 1c
3 dimes 13 nickles 5 pennies
The only simplification of (-10c-6d2) is by the integers 2 or (-2): -10c -6d2 = 2(-5c-3d2) = (-2)(5c + 3 d2)
Hc COCO maker is 1-2 coins The new coco maker the rare is 8-10c
This depends on your currency, and what denomination coins are in use. In the Eurozone there are 1c 2c 5c 10c 20c and 50c coins - as well a €1 and €2. So in tendering €1.00 and getting four different denominations in change one could get any of the following 50c, 20c, 10c, 5c. - total 85c - pencil cost 15c 50c, 20c, 10c, 2c. - total 82c - pencil cost 18c 50c, 20c, 10c, 1c. - total 81c - pencil cost 19c 50c, 20c, 5c, 2c - total 77c - pencil cost 23c 50c, 20c, 5c, 1c - total 76c - pencil cost 24c 50c, 10c, 5c, 2c - total 67c - pencil cost 33c 50c, 10c, 5c, 1c - total 66c - pencil cost 34c 50c, 5c, 2c, 1c - total 58c - pencil cost 42c 20c, 10c, 5c, 2c - total 37c - pencil cost 63c 20c, 10c, 5c, 1c - total 36c - pencil cost 64c 10c, 5c, 2c, 1c - total 18c - pencil cost 82c In US dollars there are 1c, 5c, 10c, 25c and 50c coins, as well as $1 coins This gives a smaller range of possible values 50c, 25c, 10c, 5c - total 90c - pencil cost 10c 50c, 25c, 10c, 1c - total 86c - pencil cost 14c 25c, 10c, 5c, 1c - total 41c - pencil cost 59c
The two coins are 10c and 25c. As stated in the question, one of them is not a quarter, if it's a leap year.
