Answer 1

20%

Explanation:

if you have scored 500 the first time and the second time you have 520, you could do equations to help you solve this problem.

For example:

520-?=500

500+10=510+10 more would be 520. 10×2 is 20 so the answer to

520-?=500 is 20.

the second time she took it she had 520 and you added 20 to 500. So 20 is your number.

That's how i know the increase of the score was 20%.
