Question 44809: A student receives his grade report from a local community college, but the GPA is smudged. He took the following classes: a 2 hour credit art, a 3 hour credit history, a 4 hour credit science course, a 3 hour credit mathematics course, and a 1 hour science lab. He received a “B” in the art class, an “A” in the history class, a “C” in the science class, a “B” in the mathematics class, and an “A” in the science lab. What was his GPA if the letter grades are based on a 4 point scale? (A=4, B=3, C=2, D=1, F=0)
2.7
2.8
3.0
3.1
3.2
My answer was 3.2, however their answer was 3.0. I really don't understand how they came to that answer.

You can put this solution on YOUR website! I did get 3.0
weighted average = hrs*grade + hrs*grade + . . . / total hrs
A = gpa
A = (3*2 + 4*3 + 2*4 + 3*3 + 1*4) / 13
A = (6 + 12 + 8 + 9 + 4) / 13
A = 39 / 13
A = 3.0 gpa
