Answer 1

please give me answer

Answer 2

Answer:

As per Professor Samuelson, the demand of a commodity depends on the choices that revel the preferences.  

It can be said that a consumer buys two combined goods as they are cheaper than others or the consumer likes the combination of the products.

If good x is plotted in X axis and good Y is plotted in Y axis of a graph the area covered reveals the inferiority of the choices.
