Answer:
80%
Step-by-step explanation:
home work = 10%
project grade = 50%
final exam = 40%
so
<u>homework = 72</u>
100=10
72=? cross multiply and get 7.2%
<u>project grade = 80</u>
100 = 50
80 = ? cross multiply and get 40%
<u>final exam = 82</u>
100 = 40
82 = ? cross multiply and get 32.8%
then add them altogether getting a total of 80%.
