Answer: Independent variable

   

Explanation: In simple words, independent variables refers to the variables whose variations do not depend on some other related factor.

In the given case, when the price of the premium brand decreases then the sales of brand decreases and vice -versa. However there is nothing mentioned about how the price changes.

Thus, the sales of brand depends on price but the price does not depend on the sales of the brand.

Hence from the above we can conclude that the changes in price represents the independent variables.
