Answer:

80%

Step-by-step explanation:

home work = 10%

project grade = 50%

final exam = 40%

so

homework  = 72

100=10

72=?      cross multiply and get 7.2%

project grade = 80

100 = 50

80 = ?   cross multiply and get 40%

final exam = 82

100 = 40

82 = ?     cross multiply and get 32.8%

then add them altogether getting a total of 80%.
