A college student has finished 49 credit hours with a GPA of 2.5.
To get into the program she wishes to enter, she must have a GPA of 3.3.
How many additional credit hours of 4.0 work will raise her GPA to 3.3?
:
Let x = no. of 4.0 credits required
:
= 3.3
= 3.3
Multiply both sides by (x+49)
4x + 122.5 = 3.3(x+49)
:
4x + 122.5 = 3.3x + 161.7
:
4x - 3.3x = 161.7 - 122.6
:
.7x = 39.1
x =
x = 55.857 ~ 56 additional 4.0 credit hrs, to get a 3.3 gpa (sounds almost impossible!)
:
:
Check: final total credit hr 49 + 56 = 105
=
=
= 3.3

The situation with 49 credit hours is
(49 credit hours)/(2.5 GPA) = current hours
= current hours
How many additional credit hours of 4.0
work will raise her GPA to 3.3?
Let the number of additional hours needed =

She will need 22.4 hours of 4.0 work or
more credit hours
Hope I didn't mess this up
