In this problem, it is said that a girl has just completed her second semester in college, and we are given her grades and the number of credit hours she has for each of her courses, and we need to find her grade point average.
00:16
So, first of all, let us find the total number of grade points.
00:21
Now, to obtain the total number of grade points, we need to find the sum of the products of the total scores that she got, the total number of points she got for each of her grades and the number of credit hours.
00:35
So first of all, she has a grade of d in her five -hour discrete math course.
00:40
So a d equals one point, and we multiply that with the number of credit hours, which is five.
00:47
And we want to find the total grade points.
00:50
So we add with this the grade points for the next course.
00:52
She has a grade of d in our two -hour psychology course.
00:56
So grade of d gives her one point, and there are two credit hours, so one times.

2.
01:01
Then she has a grade of a in her three -hour engineering course.
01:04
A grade of a is worth four points, and the number of credit hours is three.
01:10
And then she has a grade of b in her five -hour speech -writing course...
