Explanation / Answer

Income elasticity of demand for CD players = 0.4

The value of income elasticity of demand for CD players in Music Ville is positive. This means CD players is a normal good in Music Ville because normal goods have positive income elasticity of demand.

In case of normal good, increase in income leads to increase in quantity demanded of good.

% increase in income = 15%

Income elasticity of demand = % increase in quantity demanded of CD players/% increase in income

0.4 = % increase in quantity demanded of CD players/15%

% increase in quantity demanded of CD players = 6%

Thus,

If income in Music Ville increase by 15 percent with no change in price of a CD player, the number of CD players demanded will increase by 6 percent.

Cross-price elasticity of demand for CD players with respect to MP3s is 0.1
