How to compute grades with given data?

Hi! I am having a hard time of handling this part. Can someone please help and explain to me on how to compute grade with given data?

"A university instructor is given the task to grade three (3) groups/classes of a certain course of the same name (download the class data here:). The details of the task are as follows:

1.The grade percentages of each major activity and the final grade itself are not yet computed. The outline of the grade computation must be based on the following format:

Pre-midterm Exam (PMExam)= 10%

Midterm Exam (MExam)= 10%

Pre-final Exam (PFExam)= 15%

Final Exam (FExam)= 15%

Quizzes = 10%

Final Project= 40%

---------------------------------------------------

Final Grade (Sum)= 100%

2.The average of the quizzes (per class; variable name: AverageQuiz) must be computed first, and then the 10% score will be extracted from that computed average.

3.Add new variable names for each percentage obtained: PME10, ME10, PFE15, FE15, QU10, FP40.

4.The sum of the percentages will be the final grade, placed in a variable name FinalGrade."
