If the final counts as 2 grades and you already have 4, then you have a total of 6 grades at the end.  If you need an average of 90 on 6 tests, then you have to get a total of 6 times 90 points.  Add up the points you already have, subtract from the product of 6 times 90 to get the total points you need to score for the final.  Since the final counts as 2, divide that result by 2 to get the grade required for the final.
