The final grade for a particular course is calculated by dividing total points earned by total points available.
There are 120 points available in the first half of the course, and 140 points in the second half of the course.
If a student earns 81% in the first half of the course, how many points must
the student earn in the second half in order to earn an 80% B final grade?
:
Let x = no. of points required in the 2nd half
:
= .80
multiply both sides by 2
.81 + = 2(.80)
= 1.60 - .81
= .79
x = 140 * .79
x = 110.6 ~ 111 points in the second half
