Answer:
90.75%
Step-by-step explanation:
Given;
Of the total final score;
Quizzes = 15%
Exam = 55%
Project = 25%
Attendance = 5%
Resolving the values of each section of the total score;
she had perfect attendance to class. 100% attendance;
Attendance = 5% of total score
She got extra credit on her project with a score of 26 out of 25 possible points.
Project = 26/25 × 25% = 26%
80, 85, and 96 on the first three exams,each worth 100 points;
Total exam score = 80+85+96 = 261 out of 300
Of the total score;
Exam = 261/300 × 55% = 47.85%
At mid-semester Juanita scored 119 out of 150 points on quizzes.
Quizzes = 119/150 × 15% = 11.9%
Total exam score is;
= Quizzes+exam +project+attendance
= 11.9% + 47.85% + 26% + 5%
= 90.75%
The Total Grade value is "90.75%".
Calculating the Quizzes Score:
[tex]\to 15\% \times \frac{119}{150} \\\\\to \frac{15}{100} \times \frac{119}{150} \\\\\to \frac{1}{100} \times \frac{119}{10} \\\\\to \frac{1}{100} \times 11.9 \\\\\to 11.9\%[/tex]
Calculating the Exam Score:
[tex]\to 55\% \times \frac{( 80 + 85 + 96 )}{ (100 + 100 + 100)}\\\\\to 55\% \times \frac{( 261)}{ (300)}\\\\\to \frac{55}{100} \times 0.87\\\\\to \frac{47.85}{100}\\\\ \to 47.85\%[/tex]
Calculating the Extra Credit:
[tex]\to 25\% \times ( \frac{26}{25})\\\\ \to 1\% \times ( 26)\\\\ \to 26\%\\\\[/tex]
Calculating the attendance:
Attendance is flawless. Therefore, if overall attendance is 100, we can conclude she received 100.
[tex]\to 5\% \times ( \frac{100}{100}) \\\\\to 5\% \times 1 \\\\\to 5\%[/tex]
Calculating the Total Grade:
[tex]\to \text{Quiz + Exam + Extra + Attendance}\\\\ \to 11. 9\% + 47.85\% + 26\% + 5\%\\\\\to 90.75 \%[/tex]
Therefore, the final answer is "90.75%"
