What is this student's overall grade in the course

Answer 1

81.29%

Explanation:

Exam = 50%;

Quiz = 30%,

HW = 15% and PART = 5%

81.3% on exams, 73.8% quiz,

90% HW and 100%

therefore,

Exam total = 50×0.813 = 40.65% earned

Quiz = 300.738 = 22.14% earned

HW = 15×0.9 = 13.5 earned

PArt = 5×1 = 5% earned

Total earned = 40.65+ 22.14 + 13.5+ 5 = 81.29%
