Question

Alejandro is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 5 points. What would be Alejandro's test score (out of 80) if he got 7 questions wrong? What would be his score if he got x questions wrong?

Answer 1

Answers and Explanation:

- Total of 80 point available.

- Each question is worth 5 points.

If he gets 7 questions wrong --> he loses 7 x 5 points = 35 points.

100 - 35 = 65 --> So, his score would be 65.

If he got x questions wrong --> he would lose 5x points.

So, his score would be 100 - 5x.
