question
jamar is taking a multiple choice test with a total of 40 points available. each question is worth exactly 2 points. what would be jamar’s test score (out of 40) if he got 9 questions wrong? what would be his score if he got x questions wrong?
answer attempt 2 out of 3
score with 9 questions wrong: 22
score with x questions wrong: 2

Explanation:

Step1: Determine total questions

Total points = 40, each question is 2 points, so total questions = $\frac{40}{2}$ = 20.

Step2: Calculate correct questions (9 wrong)

Correct questions = 20 - 9 = 11.

Step3: Calculate score (9 wrong)

Score = 11 * 2 = 22.

Step4: General formula for x wrong

Correct questions = 20 - x, Score = 2*(20 - x) = 40 - 2x. For x=9, 40 - 18 = 22. For x questions wrong, score is 40 - 2x. When x=9, score is 22; the formula for score with x wrong is 40 - 2x (shown as 2 in the box? Wait, no, the "Score with x questions wrong" box: let's re-express. Wait, the problem has two parts: score with 9 wrong (22) and score with x wrong (40 - 2x, but in the box it's 2? Wait, no, maybe the user's image has a typo, but following the calculation:

For 9 wrong: total questions 20, correct 11, score 11*2=22.

For x wrong: correct is 20 - x, score is 2*(20 - x) = 40 - 2x. But the box for "Score with x questions wrong" has 2? Wait, no, maybe the question is to find the score when 9 wrong (22) and the formula for x wrong (40 - 2x, but in the box it's 2? Wait, no, perhaps the "Score with x questions wrong" is a typo, but the main calculation for 9 wrong is 22.

Answer:

Score with 9 questions wrong: 22
Score with \( x \) questions wrong: \( 40 - 2x \) (if the box was for the formula, but as per calculation, for 9 wrong it's 22)
