The average score on 7 test in algebra was 79. what was teh sum of all the scores?

OpenStudy (shamil98):

How many people were taking it? You need more info...

OpenStudy (anonymous):

\(7\times 79\) ?

OpenStudy (the_fizicx99):

The average is the mean, when you're finding the mean you divide by how many number there are, which is 7, so what ever it was x/7 = 79 So multiply it by 7, you're basically undoing it :>
