Question

What is the percent change of 80 to 100?

Answer 1

`25%` change

Explanation:

You take how much was added and divide that by how much you originally had. So in this question, from `80` to `100` was a change of `20`, so we use the equation of (change of value) / (original value).

Change of value: `100-80 = 20`
Original value: `80`
Final value: `100`

Using the equation, `20/80` we get `0.25` and multiply that by `100` to get `25%`.
