Answer 1

I don't see the equation in your question — it looks like something got dropped. Can you paste the full equation or upload the image?

Meanwhile, here are quick tips so you can identify the weekly change once you give the equation:
- If the inventory is given by a linear function like I(w) = mw + b, the weekly change is the slope m.
- If it's a recurrence like I_{n+1} = I_n + c, the weekly change is the constant c.
- If it's a formula involving a difference (ΔI = …), that right-hand expression is the weekly change.

If you paste the missing equation I’ll pick which of A–D is correct and show the steps.
