If you wanted to estimate how much money a certain appliance costs you, how would you do it?

Interesting question.

There are a number of factors that may attribute to the pricing of an item say quality of material, number of special features available, and certainly a common notion of brand value (e.g H&M vs GUCCI). Of course, it does not necessarily mean more face value = more expensive.

Typically, to estimate, I would check the brand and material component.

scientific laws are the result of testing theories and proving them to be facts.
