I come to the experts on everything I can think of help. My
teacher-wife asked me if she was calculating this correctly. I didn't
think so. What's the answer and why/how?

Chapter tests count for 60% of the final grade. Mid-term and final
tests count for 40% of the final grade. Scores for chapter tests were
80, 50 and 69. Mid-term and final tests were 80 and 90. What is the
final grade. One of us says 73.8 and the other says 80.7

Thanks


As credentialed teacher in California, I would say that it depends
if the group of grades were first averaged and then percentage taken
or were the grades totaled and then perenctages taken. And were the
perenctages averaged?
Personally, I have never gone for the averaging angle. If I see
that the total class in scoring low, I beleive in looking in the
mirror to find the problem!

I sincerely hope that your credentials don't include teaching English!
