Blinding is part of this, as the participants do not know whether they received the competitor's product.
I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y
Since you are not distributing at all, you can ignore the parenthesis :)

14x + 11
Your answer is C.
Hope this helped!
