Question

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. (1 point) Responses 2x−100 2 x minus 100 50−2x 50 minus 2 x 2x−50 2 x minus 50 100−2x/

Answer 1

To determine the student's test score based on the number of questions they get wrong (x), we start with the total points available for the test, which is 100 points. Since the student loses 2 points for every question missed, if they get x questions wrong, they lose 2x points.

Thus, the student's test score can be expressed as:

\[ \text{Score} = 100 - 2x \]

So the correct expression for the test score is:

**100 - 2x**
