Exercise 5.7.4. [W][S][Section 5.3][Goal 5.2] Ways to raise your GPA. A UMass Boston student has earned 55 credits toward his degree but has a GPA of just
1.80. The registrar has informed him that he is on probation and will be suspended unless his
overall GPA is at least 2.0 after one more semester.
(a) If he takes 12 credits, what is the minimum GPA he must earn in that semester to avoid
being suspended?
(b) Answer the same question if he takes 9 credits.
(C) What if he took just 6 credits?
(d) (Optional) What would you do if you found yourself in a similar situation take fewer
courses in hopes of doing really well in them, or take more courses so that you could afford
to do not quite so well in each?
