How do I calculate what percentage I would need to get on my final exam with these marks? Please Help?

So my calculus exam is worth 30%



I have a 87.8% in it right now, but that does not include the unit test I just took today which was worth 8%. Unfortunately I don't think I did too good on it, so consider that test around a 60%.



With those marks, what is the minimum percentage I need to get on the final exam to achieve an above 65% average in the end.How do I calculate what percentage I would need to get on my final exam with these marks? Please Help?
Ok, so since you have your exam and unit test worth a total of 38% so to find out what your currently at in the course you would multiply your mark (87.8) x the percent of how much is done in the course so (.62). This will give you what you would have if your to get zero on the test and exam 54.43, so now to get to 65 you need 10.57% more. This being said you should need to get 27.8% on both the test and exam to finish with a 65%. Since 10.57 is 27.8% of 38. And of course the better you did on the test the less you will need on the exam.How do I calculate what percentage I would need to get on my final exam with these marks? Please Help?
65-75. depends.

just study hard and dont worry about it. because in the end you know that you pushed with all your hard power and effort so that's something good to achieve even if you havent achieved nothing but at least you get to have that good feeling about yourself.How do I calculate what percentage I would need to get on my final exam with these marks?

0.62 * 87.8 + 0.08 * 60 + 0.30 * x = 65



x ≈ 19.21 on the exam (assuming the current grade is 62% of the total)
