Thank you this is correct.

I think I follow your logic @JackD'Aurizio I'm just trying to find the mistake in the last formula.

For B = 6, N = 3, C = 2, K = 2 your solution gives -22 where as the correct answer is 16. I posted this is the question.

This is interesting. Just give me a minute to work through it :)

For B = 6, N = 3, C = 2, K = 2 your solution gives -20 where as the correct answer is 16. I posted this is the question. Also this is within the B-KC <= C so should not double count.

Ah i see sorry i though it was a subscript

In my example C is 2 does this mean all the C_i are 2 as well?

What are c_i values?

Sure will check it now. I have some code for enumerating all the solutions

Is there a way to exclude the double counted solutions by find an expression for them and subtracting it?
