Math question about my mark

[From: ] [author: ] [Date: 12-06-15] [Hit: ]
7 = 7.x = 7.3 / 0.Getting anything over 24 1/3% on the remaining work will let you pass the course.......
I have a 61% in a class, with only two things left to do: an assignment that's worth 10% and the final exam which is worth 20%, totaling 30% of my mark not yet accounted for. My question is, what's the worst mark I can get on the assignment and exam without failing? A pass is 50% and above. Thanks!

Calculate a weighted average:

(0.7 * 61) + (0.3 * x) = final grade

The (0.7 * 61) is the 70% of your grade with 61% so far. The (0.3 * x) is the remaining 30%.

To get a minimum 50%:

(0.7 * 61) + (0.3 * x) = 50

42.7 + 0.3x = 50

0.3x = 50 - 42.7 = 7.3

x = 7.3 / 0.3 = 24 1/3

Getting anything over 24 1/3% on the remaining work will let you pass the course.
