Answer 1

60 points! Because 8 questions wrong would be - 40 points and its out of 100 points so 60 points

Answer 2

60 points

100 - 5x

Explanation:

If she got 8 questions wrong she missed (8 * 5) points or 40 points. This means she only got 60 points

This can be further generalized by simply subtracting the amount of questions someone got wrong by 5 from the total available points of 100

100 - 5x
