Kourtnie and kayla are sisters who are taking the same classes this semester: dre 098, chm 130/130a, and aca 122. if kourtnie earns an r in dre 098 , an w in chm 130/130a , and a b in aca 122, then what will her gpa be

W are r are not valid grades. I have attached the table associated with this question

GPA = 3.625

Explanation:
GPA stands for "Grade Point Average".
It can be easily calculated by dividing the total grade points with the total number of hours.
Taking a look at the table, we can find that:
Total grade points = 29
Total hours = 8
Therefore:
GPA = 29 / 8 = 3.625

Hope this helps :)
