Explanation / Answer

A) Price elasticity of demand = (% change in quantity demanded) / (%change in price) i) (-8/40) / (2/8) = -0.8 ii) (-5/50) / (2/8) = -0.4 B) Income elasticity of demand = (% change in quantity demanded) / (%change in income) i) (6/24) / (2000/10000) = 1.25 ii) (4/8) / (2000/10000) = 2.5
