Question 936582: If I have an 88% in algebra (403 out of 455) and I want to raise it up to at least a 90%, what would I have to get on my final exam? (I don't even know if exams count for my quarter grades in middle school, if you could answer that too that would help a lot) Thanks for your help, I appreciate it.

You can put this solution on YOUR website! No idea. We do not know how the point units are distributed among assignments and tests and final examination. We do not know how many point units is your final examination.
90% of 455 is (0.90)(455)=409.5.
You need to earn 409.5-403=6.5, better to say 7 point units.
The trouble is that, if you only take the final examination and earn 7 point units on it, this is probably too small a score on the exam compared to be number of point units that the exam would be worth. Are you expected to earn a D or F on the final examination and earn 90% of your course point units?
Best advice would be ask your teacher.
