Answers

You need 6 test scores to find the mean test score.
So we need to find the average of all the test scores.
That means we have to add all the test scores and divide by 6 because there are 6 test scores. Let’s think the the s
89+94+82+84+98+x/6=90
(X is the score that ella must have)

447+x=540
x=540-447
x=93. (Ella must have 93 test scores to have a mean test score of 90)
