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

Q=120−4P

Step-by-step explanation:

putting P = 20 we get

q= 40

we know that elasticity is quantity demanded / price

20

40

​

=2

hence the correct option: D
