 XP Math - Forums Math Question, Percent of a school mark? Help asap Plz!?

 07-24-2007 #1 swyscheese Guest   Posts: n/a Math Question, Percent of a school mark? Help asap Plz!? At my school the final exams are worth 20% of your final mark. If my mark was 58%(prior to the exam), what mark would I have to get on the final exam to pass the class?Can someone please answer the actual question behind this? (Instead of telling me how to do it)
 07-24-2007 #2 Robert C Guest   Posts: n/a Well basically here's what you can do. Say you get %100 on your test. (100x.20) = 20, add that to your 58% and you'll end up with a 78%. so for a C(70%) you would need to get a 60 on your final exam.
 07-24-2007 #3 Irfan B Guest   Posts: n/a If you get a 16% on your exam, your final grade will be 49.6%, so your teacher will probably round you up to fifty. To ensure passing, I recommend AT LEAST an 18%.EDIT: What is the passing grade where you live? I did my examples assuming you needed 50% to pass.

 07-24-2007 #5 schmiggen Guest   Posts: n/a Ask for extra credit work!It depends on what grade counts as passing, but if you need at least 70% in the class to pass, then you can't pass the class, even if you got a 100% score on the final exam. You'd have to get 118% on the final exam (for 23.6% of your final grade) to get your total grade up to 70%, so I hope your teacher gives lots of extra credit.58% of (80% of your final grade) gives you 46.4% if you get a 0% on your final exam. Multiply your final exam grade by 0.2 and add that number to 46.4, and you'll have your total grade for the class (in percent). Sorry .
 07-24-2007 #6 davemcdu Guest   Posts: n/a Assuming 60% is minimum passing percentage, you would need to get a 68% on the final.To check this, your current 58% is .8 of your total grade, so it "counts" 8 times so, 8x.58=46.4 and the final is 20% so it "counts 2 times, 2x.68=13.6.13.6+46.4= 60%
