if you have a overall 86 in your grade book and get a 95% on a test that counts for 79% of your grade how much will the overall grade (86) go up?
To calculate how much your overall grade will go up, you need to consider the weight of the test that counts for 79% of your grade. Here's the calculation:
First, calculate how much the test is worth in terms of your overall grade:
79% of 95% = 0.79 * 95 = 75.05%
Next, calculate the contribution of the test to your overall grade by finding the difference between the current grade (86%) and the contribution of the test (75.05%):
86% - 75.05% = 10.95%
Therefore, your overall grade would go up by 10.95%.
