Question

Pan's math score is 84 this time. Last time he got 70. What is the percent of increase (from last time)?

Answer 1

Answer: `" "20%`

Explanation:

You need to use the following equation:

`"% change" = "change (increase or decrease)"/"the original" times 100%`

The difference between the two marks is `14`. His original mark was `70`. This means we divide `14` by `70`, and multiply by `100%`.

We get `20%` as our percentage increase.
