<PRE><B>Question 1049694</B>
A college student has finished 48 credit hrs with a Grade Point average (GPA) of 2.75.
To get into the program he wishes to enter, he must have a GPA of 3.2.
How many additional credit hrs of 4.0 work will raise his GPA to 3.2?
:
let n = the numbers 4.0 credits required
:
{{{((2.75(48) + 4n))/((n+48))}}} = 3.2
multiply both sides by (n+48), do the math
132 + 4n = 3.2(n+48)
132 + 4n = 3.2n + 153.6
4n - 3.2n = 153.6 - 132
.8n = 21.6
n = 21.6/.8
n = 27 additional credits at 4.0
