Answer:
95%
Step-by-step explanation:
Three tests worth 100 points each = 3 X 100 = 300 points
Three quizzes worth 50 points each = 3 X 50 =150 points
Final exam worth 200 points
Total Obtainable Points=300+150+200=650
Total of test grades obtained (91, 82, and 88)=91+82+88=261
Total of quiz grades (50, 42, and 42) obtained = 50+42+42=134
Let x be the exam score for the student to obtain 90%
Therefore:
The lowest score a student can score is 190.
Expressed as a percentage of 200,
per cent
The student must score a minimum of 95% in order to make an A.
