Suppose "Hainanese chicken rice" experience an increase in price as a result of an increased demand caused by popularity of a movie of the same name. Given that "Hainanese chicken rice" and "curry chicken rice"are in competitive supply, and that the demand for "curry chicken rice" is elastic, explain the change in the total sales revenus of "curry chicken rice" with the aid of a diagram

兩隻雞野,係competitive既,前者因為有部戲幫左佢,佢果邊多人食左
咁後者因為佢話佢係elastic 既  elastic 即係話呢,你減左一個適當的價就會
令到total revenue 上升,你加左反而會令total revenue 下降,咁個圖你應該識畫了.
