Labs: together are 30% of grade
Labs 1 to 9, I got an average of 100% (so to say ... including extra credit, etc.)
2 Midterms, EACH are worth 20%
Midterm 1: 46/60 = 77%
Midterm 2: 48/60 = 80%
(curve not included yet)
Quizzes: together they are worth 5%
Quiz 1: I got a 70%
Quiz 2: I got a 90%
The final is worth 25% of our grade. It was out of 100 questions, what's the lowest possible score I could get in order to get a B?

Your cumulative score so far is:
30% * 100% + 77% * 20% + 80% * 20% + 5% * 80% = .30 + .154 + .16 + .04 = .654
You need an 80%, so on your final you need:
25% * x = .80 - .654 = .146
x = .664 = 66.4%
You need a 66.4% to get a B.
30% * 100% + 77% * 20% + 80% * 20% + 5% * 80% = .30 + .154 + .16 + .04 = .654
