Question

Find (a) the elasticity of demand and (b) the range of prices for which the demand is elastic (E , -1). f(p) = 200(30 - p)

Answer 1

elasticity of demand = \[\frac{ change \in Q }{ change \in P }\]

Answer 2

if we differentiate f(p) we ll have the elasticity

Answer 3

\[f \prime(p)=-2000\]

Answer 4

can u show it? i'm confused :/

Answer 5

i am not sure but it is the only possible solution i see here

Answer 6

ok

Answer 7

so you the answer is f'(p) = 2000 ?

Answer 8

@satellite73 can u help?
