The issue is language ambiguity, not always just math proficiency.

A "price hike" is not necessary an "increase", i.e. a sum of the old price and a change, which is X + X * (P/100). It very well might also mean "a price hike to Y", i.e. "the new price is now P percent of the old" which is a multiple (X * (P/100)).

But yeah, it's usually very confusing for all the parties involved, especially when the change is negative.

A "price hike" is always an increase, and specifically a large increase. If the value has decreased it'd be a "price drop" and a large drop would be a "price slash".

Yeah, that's the point, ambiguity.

Again, what I meant is, of course, "price hike" in itself always constitutes some increase, but its nature can be one of two: 1. positive delta 2. setting the price to a ratio > 1.
