To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course. Suppose a student had these grades:
3.7 in a 5 credit Math course2.6 in a 3 credit Music course3.1 in a 5 credit Chemistry course3.2 in a 5 credit Journalism course
What is the student's GPA for that term? Round to two decimal places.
