What is the equation you use to find what grade you need to get on a Final to maintainbring up your grade?

It depends on the weight given to the Final Exam. However, Here is an example where there are three components to the final grade, Attendance, Quizes and the Final Exam: {D - W(A) - X(Q)}/Y = Grade Needed on Final Where D = your desired final Grade. W= the weight given to Attendance (like 20%) and A=your current Attendance grade. X=the weight given to Quiz grades (like 30%) and Q=your current Quiz grade. Y=the weight given to the Final Exam (like 50%) W + X + Y must = 1 (100%) So, if you want to end up with a final grade of 90, and your Quiz scores average 80 but you have a 100 in Attendance, the formula is: {90 - .2(100) - .3(80)}/.5 = (90-20-24)/.5 = 46/.5 = 92 grade neede on Final If there are more than 3 components, the weight and current grade would go into the formula just like W(A) and X(Q), as a subtraction from D. Just make sure that all your weights always add to 1.
