Question

nayeli is taking a multiple choice test with a total of 20 points available. each question is worth exactly 2 points. what would be nayelis test score (out of 20) if she got 4 questions wrong? what would be her score if she got x questions wrong? answer attempt 1 out of 2 score with 4 questions wrong: score with x questions wrong:

Explanation:

Step1: Find total number of questions

Total points = 20, each question is 2 points. So number of questions = $\frac{20}{2}$ = 10.

Step2: Score when 4 questions wrong

Points lost for wrong questions = 4 * 2 = 8. Score = 20 - 8 = 12.

Step3: Score when \( x \) questions wrong

Points lost for \( x \) wrong questions = \( 2x \). Score = 20 - \( 2x \).

Answer:

Score with 4 questions wrong: 12
Score with \( x \) questions wrong: \( 20 - 2x \)
