Question

A student with a 1.875 gpa has 24 credit hours. Find out how many credit hours of b's (at 3 points per credit hour) he will need to raise his gpa to a 2.40

Answer 1

1.875 = totalqualitypoints/24
or total quality points to date is 45

2.40= (45+3*New)/(24+New)

where new is the number of new B's (No A, no c, d, or f)

solve for new
