Question

Christopher is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 2 points. What would be Christopher's test score (out of 100) if he got 10 questions wrong? What would be his score if he got xx questions wrong?

Answer 1

Score with 10 questions wrong: 80

Score with x questions wrong: 100−2x

Explanation:

each point is deducted by 2 pts and so, with 10 question, he got an 80.

100 is the availability of the points and 2x means which the points were lost

Answer 2

If im not wrong, if every question is 2 points of 100 points in total means that are 50 questions, so if he gets 10 wrong then he would be losing 20 points which his final grade would be 80!
