Question

Transcribed Image Text:3. For each of the following demand curves:
i) Find the price-elasticity of demand in terms of P.
ii) Determine the range of P values for which the de-
mand curve is perfectly elastic, elastic, unitary elas-
tic, inelastic and perfectly inelastic (your answer will
look like, the demand is inelastic for 0 < P < 10,
unitary elastic at P = 10, etc).
iii) Calculate the price-elasticity of demand at P = 3
and give an interpretation in words of what that
means in terms of percentages.
E
(a) Q(P) = 77 – 2P
(b) Q(P) = 5P−½/
(c) Q(P) = a - bP
