10 a. What is the price elasticity of her demand for clothing?
10 b. What is the income elasticity of her demand for clothing

Expert's answer

If Layla spends 25% of her income on clothes,regardless of the price of clothes, and regardless of her income each year:

a) Her demand for clothes is unit-elastic, because if price increases, the quantity demanded will decrease proportionally, so Ed = 1

b) Her demand for clothes is also unit-elastic, because for any change of income, the percent change of the quantity demanded will be the same, so Ei = 1

a) Her demand for clothes is unit-elastic, because if price increases, the quantity demanded will decrease proportionally, so Ed = 1

b) Her demand for clothes is also unit-elastic, because for any change of income, the percent change of the quantity demanded will be the same, so Ei = 1
