A student takes a 50 question test. Each question is worth two points that means the whole test is worth 100 points in the student loses two points for every question Miss write an expression to find the students test score if they get X questions wrong.
Let's denote the number of questions the student gets wrong as X. Since each wrong question deducts 2 points from the student's score, we can calculate the points lost by multiplying X by 2, which gives us 2X.
To find the student's test score, we subtract the points lost from the total possible points. The student can earn 100 points on the test, so the expression to find the student's test score would be:
100 - 2X
