Question

Elijah is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 2 points. What would be Elijah's test score (out of 100) if he got 8 questions wrong? What would be his score if he got xx questions wrong?

Answer 1

Explanation:

Answer 2

84 points

y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)

Explanation:

100- 2(8) = y

100-16 = y

84=y

Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)
