transferred 20 credits with a GPA of 1.5 from the juvenile detention center.Has since earned 25 credits since with a gpa of 1.9.
how many credits with a 2.5 average would he need to raise his gpa to 2.0
--------
Equation:
(20*1.5 + 25*1.9 + x*2.5)/(20+25+x) = 2
--------
(30 + 47.5 + 2.5x) = 90+2x
-----
77.5 +2.5x = 90+2x
0.5x = 12.5
----
x = 25
----
Needs 25 credits with a 2.5 average
