How many different coin combination could a person have is she has 21 cents and what is each combination?

Question

Make sure to list them all if you can.

Answer 1

10 + 10 + 1

5 + 5 + 10 + 1

5 + 5 + 5 + 5 + 1

And there's more, if you take each of the above an rewrite the non-penny portion in terms of pennies. For example for the first one:

10 + eleven 1's

In this work, 1=penny, 5=nickel, 10=dime

I've started this for you and told you how you can find some more. I can't do your entire problem for you as I'd be robbing you of the learning experience. Please try to find some of the other answers on your own - it will be good practice for you.

Answer 4

It's not possible to describe them all.

Just on the one that involves the fewest coins, two dimes and a penny.... Have you any idea how many dimes and pennies are in circulation?

The number of combinations is practically infinite.

Answer 5

I came up with nine total combinations. I used "d" to denote dimes, "n" to denote nickles, and "p" to denote pennies. The combinations are as follows:

2d+1p

1d+2n+1p

1d+1n+6p

1d+0n+11p

4n+1p

3n+6p

2n+11p

1n+16p

0n+21p

Answer 6

10, 10, 1

10, 11
5, 5, 5, 5, 1
5, 5, 5, 6
5, 5, 11
5, 16
21 pennies

Answer 7

my advice is to do it yourself, because it isn't hard just time consuming
plus everyone here is too lazy to do it either (although there are exceptions, not to say that they are bad)
