You can put this solution on YOUR website!
If 85% of your grade is 67, what do you need on the other 15% to have an average of 72%?
.
Let's say there are a thousand points in the class. Out of 850 already awarded, you have 569.5 (67*85=5695)
.
You're after 72% of 1000, or 720.
720.0 - 569.5 = 150.5
You need 100%. All 34. Study hard!
