Yes, I got 600 with a regret of $180

Can you remember what’s your contribution?

Hey can I know how you get the 5.8 – 1.6 as your contribution? I did it the same way with you but I remember my contribution was 3 point something. Do you remember any figure like this? I use selling price minus the cost of production.
