yeah you have to to distinguish whether $1 is the books normal price and the book is being sold at a premium or whether $1 is a fraction of its final price. If you don't specify you end up with rage-bait, which I think is probably the purpose of the question to begin with (just like that stupid 6 ÷ 2 ( 1 + 2 ) equation that goes viral on Twitter every few months).The best way to word the problem would be "the price of the book is 1$ plus half of its final price" but the general consensus is that it's equal to 2. Not sure who voted 1.5 ngl
I voted 1.5 on reflex when I first saw it, but upon reflection I think 2 makes more sense with how I subjectively read it. Can't go back and change my vote though, so I'm stuck in the 1.5 crew.
