In Marissa's calculus course, attendance counts for 10% of the grade, quizzes count for 20% of the grade, exams count for 55% of the grade, and the final exam counts for 15% of the grade. Marissa had a 100% average for attendance, 89% for quizzes, 82% for exams, and 81% on the final. Determine Marissa's course average.

.10*100 + .20*89 + .55*82 + .15*81 ≈ 85

I would do it this way:
1.0(.1) + .89(.2) + (.82)(.55) + .81(.15)
= .8505
or 85%
