This isn't a math problem but my math final is tomorrow and I need some help. If there are 510 points possible in the assignment course, and 200 points on the final. I have a 385 points in the assignment course giving me a 75%... If I get a 45% on the final, what would my over-all grade be? Thanks!

Question

anonymous · Answer

.45*200 = 90 pts.
385+90 =   475
475/510 = 93.1

anonymous · Answer

or maybe my question should be, what grade do i need to get on the final to have a 70% or higher?

anonymous · Answer

youve already passed the class.

385/510 = 75%

anonymous · Answer

and i believe the 200 final points will be tacked onto the 510 making it 720... sorry about that

anonymous · Answer

oh oh, my bad.

anonymous · Answer

i mean 710** wow i am bad at math! lol

anonymous · Answer

ok, so we want to solve:
$$\frac{385+x}{710} = .70$$
to figure out what you need in order to get a 70 in the class

anonymous · Answer

wow, i don't see how you do it! amazing lol

anonymous · Answer

this turns into:
$$385+x = 497 \Rightarrow x = 497 - 385 = 112$$

anonymous · Answer

that means id have to make a 112?

anonymous · Answer

yes, you need to score at least a 112.  higher and you pass, lower and you dont.
112/200 = .56  which is 56%
So its like saying you need to get a 56 on the test.

ok, i can probably handle that hopefully, 20 question test, multiple choice! Thank you!
