What does delta mean here? Change? Differential operator?

The change in

So it should be as P changes by an arbitrary number N, c is changed by 14*N

@LS1088  I'm afraid i don't quite understand!

anonymous · Answer

It should be simple as it is basic multiplication? @_@ 
So say P is initially 5, therefore C = 70;
P increases by 1, C increases by 14;
P decreases by 1, C decreases by 14;

What if p changes by 7 how much would c change? @LS1088

anonymous · Answer

7*14, as C is a simple linear function of P
