Ben is taking three AP classes and two regular classes. His AP classes count twice as much as his regular classes in his GPA. Ea
zhannawk [14.2K]
This problem deals with a weighted average. Since the AP classes count twice as much as regular classes, their grades must be counted twice. It's as if for each AP class he's taking, he was taking two classes. The points of each AP class grade is added twice, and the each AP class counts as 2 classes in the number of classes.

Each AP class counts twice and counts as 2 classes.

Class                                Ben's grade     Points          Number of Classes
AP English                               B               3 + 3                         2
AP Government                       B               3 + 3                         2
AP Algebra II                           A                4 + 4                         2
Spanish                                   B                   3                            1
Physics                                    D                  1                            1
TOTALS                                                       24                           8

GPA = (total points)/(number of classes) = 24/8 = 3
