Question 928494: My overall grade is a 80B. Our final weighs 30% . Whats the lowest I can make and still pass with a C?

Assuming C is 70% or above and your 80% currently covers 70% of the grade (otherwise not enough info):

.80(.7) + x(.3) = .7
x = .4666...

You would need at least a 47% to pass with a 70%.
