three of four numbers total 22. If the average of the four numbers is 8, what is the 4th number ? I got 10.....is that correct ?
yes 10 is right answer.
I set it up like this... (22 + x)/4 = 8
Yes. Since the four numbers average 8, the sum of the 4 numbers has to be 32. Your answer seems to check out.
great...thank you so much for confirming
