Question

Penelope is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 5 points. What would be Penelope's test score (out of 40) if she got 3 questions wrong? What would be her score if she got x x questions wrong

Answer 1

25pts

Explanation:

Answer 2

see below

Explanation:

She got 3 questions wrong

3*5 = 15

She missed 15 points

40-15 = 25

She got 25 points right

25/40 =.625 =62.5%

If she got x questions wrong

5x is the points missed

40 -5x is the points correct

(40-5x)/40 = score
