Caroline is taking a multiple choice test with a total of 40 points available. Each question is worth exactly 5 points. What would be Caroline's test score (out of 40) if she got 2 questions wrong? What would be her score if she got x questions wrong? (Linear Expression from Context) help!!!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
