Answer :
Jayne's GPA is calculated by considering that her AP classes count twice as much as her regular classes. Her total points are divided by the total weights to find the GPA, which rounds to 2.6.(option A)
To calculate Jayne's GPA considering that AP classes count twice as much as regular classes:
- AP English (C): 2 points, counts double, so: 2 x 2 = 4 points
- AP Govt. (B): 3 points, counts double, so 3 x 2 = 6 points
- Algebra 2 (B): 3 points
- Spanish (D): 1 point
- Physics (A): 4 points
Now, we add up all the points:
- 4 + 6 + 3 + 1 + 4 = 18 points.
Next, we add up the weights for each class: AP classes count double, so:
- 2 + 2 + 1 + 1 + 1 = 7.
Finally, we calculate the GPA by dividing the total points by the total weights:
- GPA = 18 points / 7 = 2.57.
Jayne's GPA rounded to the nearest tenth is 2.6.
The correct answer is A. 2.6.
