.Final Exam - 25% Tests: Decimal = 0.4, and average - 70, then 0.4 x 70 = 28 . Suppose you averaged the grades for each FN: Decimal = 0.25, and average = 60, then 0.25 x 60 = 15 area and found out the following results: Homework - 90, 70, 80 Step 4: Sum all results: we will add weighted average HW = 20, Classwork - 95, 85, 80 100 CW - 9, Tests - 28, and FN - 15. Then the final average (FA) is Tests - 80, 60, 70 Final Exam - 60 FA = 20+ 9+28 + 15 = 72 (HW 90, 0, 100, 80, 100, 80 ). Then homework's average = (90 + 0 + 100 + 80)/4 (HW 90, 0, 100, 80, 100, 80 ). Then homework's average = (90 +100 + 80 )/3 O (HW 90, 0, 100, 80, 100, 80 ). Then homework's average = (90 + 0 + 100 + 80+ 100+ 80)/6 O (HW 90, 0, 100, 80, 100, 80 ). Then homework's averages (90 + 100 + 80+ 100 + 80)/5
