Question

Bao is taking a multiple choice test with a total of 100 points available. Each question

is worth exactly 2 points. What would be Bao's test score (out of 100) if she got 8
questions wrong? What would be her score if she got x questions wrong?

Answer 1

84

Explanation:

100-point test = 50 questions which are worth 2-points each.

(50 x 2 = 100)

If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)

100 - 16 = 84

To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.
