1. For what income are the demands of these commodities changing the most? 

2. For what income are their variations the least? 

3. What commodities (from the ones you chose) have been impacted the most by inflation in the last three years? 

4. What is the rate of change of these products with respect to income? 

5. In the light of your results above, to whom would you say that the impact of inflation is greater?
