10c-4c = 6
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.
In a 2 dollar coin there are 20 10c coins in it
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
That depends on the value of f.
