Question 795807: If you are given an average for 5 tests and then one test score is deleted from the average and you are given a new average of the four remaining scores, how to you compute the grade on the deleted test?

You can put this solution on YOUR website! let x be the average of 5 tests and
y be the average of 4 tests, then
5x -4y = the grade of the eliminated test
