if you have a overall 86 in your grade book and get a 83% on a test that counts for 21% of your grade how much will your 86% overall grade go up?
To calculate how much your overall grade will go up, you need to determine the weighted value of the test and then calculate its effect on your overall grade.
First, find the weighted value of the test by multiplying the test score (83%) by the weight (21%):
Weighted value of the test = 83% * 21% = 0.83 * 0.21 = 0.1737
Then, calculate the grade increase by multiplying the weighted value of the test by the overall grade:
Grade increase = 0.1737 * 86 = 14.9192
Therefore, your 86% overall grade will go up by approximately 14.92% after getting an 83% on the test.
