1. Find the price elasticity of supply at price of Birr 8 if the supply function is: Q = 25 – 4P + P2 What is elasticity at Birr 4 and at Birr 5? Interpret the result.

1) Elasticity of Demand: a) Define and calculate price elasticity of demand using the mid-point method. b) Discuss the determinants of price elasticity of demand and their impact on the degree of elasticity. 21 c) Provide real-world examples illustrating the concept of price elasticity of demand.

K Use the price-demand equation to find E(p), the elasticity of demand. x= f(p)=90-0.8eP E(p)=

DE According to the income elasticity formula, Income elasticity of demand = E=% change in quantity demanded + % change in income. By how much will popcorn sales increase if average income goes up by 9 percent? (Assume the income elasticity of popcorn is 3.29.) Instructions: Enter your response as a percentage rounded to one decimal place. percent
