Astudent received the following grades last semester. find the student's semester grade point average. an a is algebra (3 credits), a b in history ( 3 credits), a in sociology ( 3 credits) a d in english ( 3credits) and a c in seminar ( 2credits). an a is worth 4 points, a b is worth 3 points a c is worth 2 points and a d is worth 1 point.

If it is a simple average, the average is 2.8 points.

If it is a weigthed-by-credits average, the average is 2.86 points.

Step-by-step explanation:

To calculate the simple average of this 5 grades, we sum all the points and divide it by 5:

In Algebra: A = 4 points

In History: B = 3 points

In Sociology: A = 4 points

In English: D = 1 point

In Seminar: C = 2 points

Average = (4+3+4+1+2)/5 = 2.8 points

If the average is weighted by the credits, we must add each score multiplied by the credits and, in total, divide it by the total amount of credits.

answer: 88
