A college student takes the same number of credits each semester. She had 12 credits when she started, and after semesters, she had 96 credits.
Which of these expresses the rate at which she is earning credits?

The student obtains his 12 credits each semester during 8 semesters.

Step-by-step explanation:

Since a college student takes the same number of credits each semester, and she had 12 credits when she started, and after

semesters, she had 96 credits, to determine the rate at which she is earning credits, the following calculation must be performed:

96/12 = 8

Thus, the student obtains his 12 credits each semester during 8 semesters.
