Sarah is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Sarah's test score (out of 50) if she got 10 questions wrong? What would be her score if she got x questions wrong?
Score with 10 questions wrong:
Score with x questions wrong:
If Sarah got 10 questions wrong, she would lose 10 * 2 = <<10*2=20>>20 points.
Therefore, her test score would be 50 - 20 = <<50-20=30>>30 out of 50.
If Sarah got x questions wrong, she would lose x * 2 points.
Therefore, her test score would be 50 - x * 2 out of 50.
