Homework Statement
How should I interpret the derivative of the following function at C=6%
##N = \frac {I} {C} - D##
Homework Equations
## \frac {dN} {dC} = \frac {-I} {C^2} ##
At I =12 and C=6%, I am getting
## \frac {dN} {dC} = 3,333 ##
I am not sure what to make of this large number. I want to be able to say for every 1/100th increase in C, N changes by X dollars, or something like that. The following document, for example, shows one such example.

How can I interpret the 3,333 figure?
