If price declines from $400 to $ 300 and quantity of demand increases from 1100 to 1400 then what is the elasticity of demand

Answer 1

its answer is 1.09

Answer 2

Price elasticity of demand = Proportionate change in quantity demanded / change in price

Proportionate change in quantity demanded = 1400 - 1100 = 300

Change in price = 400 - 300 = 100

Price elasticity = 300/100

= 3

Price elasticity of demand is thus :

3
