If my grade in my ENTIRE MATH CLASS is a 76 and a test weighs 35% what would be my new math class grade
To calculate your new grade after the test, you can use the weighted average formula:
New grade = (Current grade * (1 - Weight of test)) + (Test grade * Weight of test)
New grade = (76 * 0.65) + (X * 0.35)
New grade = 49.4 + 0.35X
Since you want to know what your new grade will be after the test, you can plug in the test grade (let's say the test grade is an 85):
New grade = 49.4 + 0.35(85)
New grade = 49.4 + 29.75
New grade = 79.15
Therefore, your new math class grade after the test with a score of 85 will be approximately 79.15.
