Answer:
75
Step-by-step explanation:
First, turn everything into a decimal to make it easier. Since everything is a percentage, all you have to do is move the decimal point left twice.
0.93
0.82
0.72
0.60
Now you do the same for the weighted percentages and multiply them by the decimal for that subject.
Homework: 0.93*0.10=0.093
Quizzes: 0.82*0.30=0.246
Tests: 0.72*0.40=0.288
Final Exam: 0.60*0.20=0.12
Now add them altogether.
0.093+0.246+0.288+0.12=0.747
Now turn it back into a percent.
74.7%
Round up.
75%
