Answer 1

Answer:

Freshman: 3.245

Sophomore: 3.0775

All:  3.16125

Step-by-step explanation:

Freshman: (B+) + (B+) + (A-) + (B-) /(4lessons)

(3.33 + 3.33 + 3.66 + 2.66)/4=12.98/4=3.245

Sophomore: (B-) + (C+) + (A-) +(A-) /4

(2.66 + 2.33 + 3.66 + 3.66)/4 = 12.31/4= 3.0775

All: (3.245 + 3.0775)/2=6.3225/2=3.16125
