The demand curve for a good is Q = 100 - 2p

Economics Dec 18, 2020

The demand curve for a good is Q = 100 - 2p. What is the elasticity at the point p = $12.00 and Q = 76? The elasticity of demand is?

Expert Solution

PED= (change in Quantity /change in Price) * (Price / Quantity)

Change in Quantity /change in Price = -2 (obtained by differentiating the demand equation (Q = 100 - 2p)

Price = 12

Quantity = 76

Hence, PED = (-2) * (12/76) = -0.3157
