The graph below shows the cost (C) of packets of juice (N).

Preview Chart

Complete the formula: C=___N

I have two answers for this, but I'm not sure which one is correct. Hare are my answers:

(1) C= k*N (k stands for constant)

C=180, N=12

180=k*12

180/12=k

15=k

C=15*N

Ans= C=15N

(2) C=k*N

C= 180, N= 18

180=k*18

180/18=k

10=k

C=10*N

Ans= C= 10N

Which answer is correct?

Ok, maybe I can't make you see the graph, but I can tell you what's on it. Ok, on the X axis it is labelled Number of Juice (N) Y axis is labelled Cost in Rupees (C). On the X axis it starts at 0 then goes on to 2, 4, 6, 8, 10, 12, 14, 16, 18. And on the Y axis it starts at 0 and goes on to 20, 40, 60, 80, 100, 120, 140, 160, 180. It's a line graph. Now the line starts at 0 and goes up to 180 and is in line with 12, it doesn't go on to 18. Is that a good description?

We can't tell; we can't see the graph!

That's weird, I can see the graph just fine. Let me see if I can do something about it.

Do you mean it's like this:

 

 Line graph:

If so, your first solution is correct.
