In my math work book there’s a section on, when translated into english, “percentage change factor”. I am looking for the actual name for it in English in order to search more info/help regarding this.
I am not talking about: change/Original price for example 1320-320/1320.
I want to know what this is called:
Change factor = New value/old value: 1200/1900 = 0.631
The 0.631 is the “change factor”.
Or
A camera cost $3750. The price was increased by 12%. What was the new price?
100% + 12% = 112%
The “change factor” is 1.12
Does anyone know what the actual name for the “change factor” in English?
