I found this exercise online, from a website I use all the time. Usually it’s a great resource but I a bit confused about a solution they provided.

Essentially the question was asking: “Calculate by what percentage costs will be reduced.“

The price the question started with was $191.85.
The reduced price was $28.50.

The solution for this question now say that the price will be reduced by 0.15 -> 15%. (Dividing 28 by 191.85)

But shouldn’t it be 85%?

15% percent of 191,85 are 28.50 but that would mean that the reduced price is about 163? Not 28.50.

This happens fairly often to me, when I am in overwhelming environments like a busy room or mall but also when I am in heat for too long, like on a hot summer day.
I constantly “zone out“ and can’t really focus on anything or react to what someone is saying/doing.

The problem is that I doesn’t go away when I leave the situation. It can still affect me hours later, and I have no idea what to do about it.

Dae have tips on this?
