You can put this solution on YOUR website!
If you currently have an average of 91, then your current mark is 91. Current means right now, the latest thing, the mark you have after all tests are considered. Now if you actually meant that your mark PRIOR to taking the last test was 91, and your last test had a score of 26%, then you have not provided enough information to be able to calculate your current mark. You would have to provide the number of tests and assignments and the relative weight of each that comprise the mark of 91.
If there were ten assignments of equal weight that resulted in the average of 91, then after the last test you would have 936 points, which, when divided by 11 would yield an average of 85.1 (rounded to the nearest tenth). But on the other hand, the 91 consisted of two quizzes, a midterm that counted twice as much as either quiz, and a term paper that was worth 3 quizzes, you would have 637 points. To this you would add some multiple of 26 depending on the relative weight of the last test you took.
I have described two situations out of many thousands of possibilities. Do you understand why you have not provided enough information?
