Hej NG, - håber i vil hjælp mig med denne nød.. Har vist set mig blind på
den :o/

In short, the UK market for butter can be described from the equation:

Qs = 21,39 - 10,88 Ps + 12,36 Pm+ 0,29 Y


Qs = is the quantity of butter sold in grams per person per week
Ps = is the price of butter in £ per 250 grams
Pm = is the price of margarine in £ per 250 grams
Y = is the index of the real income (index 2000 = 100)


a) Find the consumption in 2003 in grams per person per week when

Ps = £0.60 per 250 grams
Pm = £0.40 per 250 grams -
Y = Index of the real income is 105 for 2003


b) Find and characterize the price elasticity by Ps = £0.60 per 250grams

c) Find the cross-elasticity and the income elasticity, make a graphing
of them and characterize them - use the information in a)



a) = 45.5g ik..?

b) = -0,0527 ik...?

c) = ?

Jeg har lavet lektier hele dagen, og hovedet er ikke helt skarpt.. Nogen der
vil hjælpe?

På forhånd tak
