Look for "weighted average"

I think you are saying: you got 72%, 100%, 58% and 73% on quizzes,
homework, participation and final respectively, and you want to know
your total score given that quizzes count for 40% of the total and the
other categories count for 20% each. The following is one way to
compute the answer:

=sumproduct({0.72, 1, 0.58, 0.73}, {0.4, 0.2, 0.2, 0.2})

Of course, you can replace the constant arrays with ranges, if the
values are stored in cells.
