A particular student has a grade point average (GPA) of 2.5 in their first three courses.What is the minimum average they will need in their fourth and fifth courses so that their overall GPA on all five courses is at least 3.0?

A) 3.00
B) 3.25
C) 3.50
D) 3.75
E) It cannot be determined.

To achieve an overall GPA of at least 3.0 across five courses, the student needs a total of 15 grade points (since 3.0 * 5 courses = 15 points). The student already has 7.5 points from the first three courses (2.5 GPA * 3 courses). Therefore, they need 7.5 more points from the next two courses, which means they need an average of 3.75 per course (7.5 points / 2 courses = 3.75).
