If I have an 88 ( third 9 weeks) and 83 (forth 9 weeks) and the average of these two only counted 80% of my final grade, what would that 80% grade be?
-
the average of 88 and 83 is 85.5
80% of this is 68.4
So, for the remanining 20% of your grade as long as it is at least a 58 - you will have an 80 average.
Looks like you're set for a B

.80 ((88+83)/2)
.8(85.5)
=68.4 points. If you make a 100 on the next 20%, you can make a maximum grade of 88.4. This can go up if your teacher/professor rounds that 85.5 to an 86. If he/she round before multiplying times .8, it is to your advantage.

88+83 = 171
171/2 = 85.5%
.8 * 85.5 = 68.4%
171/2 = 85.5%
.8 * 85.5 = 68.4%

you got 68.4 of final grade
