I am doing a project for math class and it is asking for the relative change. In our book, the formula is relative change = new value - original value/original value.

Question

The project is we look up nutritional values of items at a restaurant and then we have to estimate values based on calories of fat, carbs and protein.

What I'm having trouble with understanding is this: what is considered my new value and what is considered my original value?
I have the value provided by the restaurant and I have the value I calculated.

Thank you.

Answer 1

you have a change, right?
Suppose you change from 6 to 10
The actual change is 10-6 = 4
The relative change is thus 4/6 or 67%
That is, 6 was increased by 2/3 of its value
