Answer:
The price elasticity of demand is -0.25
Explanation:
The demand equation is given by:
Q = 80 - 0.25p
The price elasticity of demand is the same as the rate of change of Q (Quantity demanded) with respect to p (price).
The rate of change of Q with respect to p is obtained by differentiating Q with respect to p
Q = 8 - 0.25p
dQ/dp = -0.25
Therefore, price elasticity of demand = -0.25
