Question 973635: I have a 105 average and if I got a 77 on a test, what is my new average?
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! I can't answer this without knowing how many tests comprised your average. If only one prior test, your average is the sum divided by 2, or 182/2 =91.
If, however, you have taken more tests, you can't average two numbers if they are not weighted the same.
