Question 763458: Manuel has scored 82, 91, 73, 75, and 93 on his previous five tests. What score does he need on his next test so that his average (mean) is 81.

You can put this solution on YOUR website!
Add all 5 scores = 414
Mean of the 6 scores = 81
6 * 81 = 486
486 - 414 = 72
So, Manuel needs to get 72 for his next test
to achieve a mean of 81
Hope this helps.
