Jill took five courses this semester, each for four credit hours.
She received a B (3 points) a B+ (3.5 points), an A (4 points), and a B+ (3.5 points) in four of the courses.
If her GPA is 3.2, what was her grade in the fifth course?
Let x = the grade of the fifth course
multiply both sides by 5, add the 4 grades
14 + x = 5(3.2)
x = 16 - 14
x = 2.0 for the 5th course
