Answer 1

Answer:

Step-by-step explanation:

Exams:                         20% times 73  =        14.60

Term papers:               10% times 83              8,3

Final:                            70% times 92           64.4

Final Grade (Weighted Average) =               87.3

All the grades were figured as follows

Final 92 * 70/100  = 6440/100 = 64.4
