Question

The demand function is given by
D = 20 - p-p2 where D =
demand and p = price. Find the
elasticity of demand w.r.t. price
when price is 2​

Answer 1

Answer:

Q=120−4P

Explanation:

putting P = 20 we get

q= 40

we know that elasticity is quantity demanded / price  

20

40

​  

=2

hence the correct option: D
