    You need to do an average of all credits in one calculation. You can't do an average of averages.

    Let x = number of additional credits the student needs to get 4.0 GPA on. 52 credits with a GPA of 2.8 means a total of 52 * 2.8 = 145.6 \(\dfrac{145.6 + 4x}{52 + x} = 3.2\) Solve the equation for x.
