a student takes a 50-question test. each question is worth 2 points. that means the whole test is worth 100 points, and the student loses 2 points for every question missed. write an expression to find the student's test score if they get x questions wrong. A 100 - 2x. B 2x - 50. C 2x - 100. D 50 - 2x.
The correct expression to find the student's test score if they get x questions wrong is A) 100 - 2x.
We can break it down as follows:
- The total score of the test is 100 points.
- For each question the student gets wrong, they lose 2 points.
- This means that for x questions wrong, the student will lose a total of 2x points.
- To find the student's test score, we need to subtract the points they lost from the total score of 100, giving us 100 - 2x.
