Question

Bart has a pa of 1.5 so far for the year for 20 credits. What grade point does he need for his remaining 10 credits to get a 2.0 for the year and avoid summer school?

Answer 1

Let X represent the GPA needed on the last 10 credits to raise the overall GPA from a 1.5 to a 2.0

The formula for the new average becomes

(20 credits * 1.5 + 10 credits * X)÷(20 + 10) =2.0

(20 credits * 1.5 + 10 credits * X) = (20 + 10) * 2.0

30 +10 X= 60

 

 X= (60 -30)÷10 = 3

 

so the GPA needs to be at least 3.0 for the remaining 10 credits for Bart to avoid summer school 

 

2 = .2 X or X = 10 so Kodos needs 10 credits of 3.5 GPA added to his 20 credits of 3.2 GPA to obtain an overall GPA of 3.3 at 30 hours
