Let the first course unit be x1 , second be x2 and so on.. Therefore, (X1 + x2 + ….. + x46 )/46 = 3. 19 (X1 + x2 + ….. + x46 ) = 3. 19*46 = 146. 74 Also, (x47 + x48 + ……+x58)/ 12 = 3. 8 (x47 + x48 + ……+x58) = 45. 6 Therefore, Tessa's cumulative GPA fro all 4 semesters will be the sum of all course units divided by 58(46+ 12) Therefore, (X1 + x2 + ….. + x46 + x47 + x48 + ……+x58)/ 58 = (146. 74 + 45. 6)/ 58 = 192. 34/58 = 3. 316 Hence her GPA for all 4 semesters- 3.32
