Question

Quizplus · Accepted Answer

To find the grade in the fifth course, calculate the total points Jill has earned and then subtract the points from the courses we know about. Jill's GPA is 3.4 across 5 courses (each 4 credit hours), so total points = GPA * total credit hours = 3.4 * 20 = 68 points. From the known courses, she earned 3*4 + 3.5*4 + 4*4 + 3.5*4 = 56 points. Subtracting this from the total gives us 68 - 56 = 12 points for the fifth course, which, since it's also a 4 credit hour course, means she earned 3 points per credit hour in it, corresponding to a B grade.
