economics paper 2

I don't consider that sign is necessary as in the book of Susan grant it was written somewhere in the elasticity chapter that sign is obvious so it's not necessary to put it in ped.

Really? From what i heard, they give 1 mark for sign and 1 for the figure..

There are 2 steps to the question, the correct formula and then consequently the correct answer, hence 2 marks. Can't imagine them being allocated in another way i mean it's pretty straightforward to me
