An average is worked out by dividing the total of the scores by the number of scores.

You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450.

The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test.

The average for the first 4 tests comes out at 88.5

How do i average my grade when my grade is a 84 and my final was a 73 the finals worth 25 how do i find out my grade?

Missing information - you need the worth (weight) for every grade, not just for some of them. The way you calculate this so-called "weighted average" is to multiply each grade by its weight, and add everything up. Then you divide by the total "weight". Example: exam 1: grade is 80; weight is 40. exam 2: grade is 70; weight is 60. 80 x 40 + 70 x 60 = 3200 + 4200 = 7400. Divide this by the total weight (40 + 60 = 100), and you get a weighted average of 74.


If I have a 77 percent in class and normal tests are worth 50 percent of your grade the final exam is 20 percent What grade will I need to get on the final and normal exam to get an 87 in the class?

you would need anything higher than an 87 because its an average and if you get lower there is no way it can get to a 87.


If the final is 15 percent of grade and have an average of 100 what score do you need to get at least 90 in the class?

You do not even need to get a 30% on the final. If you have a 100% in the class and get a 0% on the final, you willl still have an 85% in the class.

How can I figure out my grade for my final?

If all your grades are weighted the same you add all of your grades together, then divide it by the number of grades you have for example: 97 82 35 67 86 43 (my grades not really) divided by 6 because that is how many grades i have = a 68% 68% is my final grade. If they have different weights then you need to multiply the grade by the % its worth.
