If your grade in math is 83% how much will a assignment with 17% weight raise your grade up if you get 100
Assuming the assignment is the only grade that will be affected and all other grades remain the same:
Current grade: 83%
Weight of assignment: 17%
Grade you will get on assignment: 100%
You can calculate the new grade using the formula:
New grade = (Current grade * Current weight) + (Grade on assignment * Weight of assignment)
New grade = (83% * 83) + (100% * 17)
New grade = (68.7) + (17)
New grade = 85.7%
So, your grade would raise to 85.7% by receiving a 100% on an assignment with a 17% weight.
