A student has a mean score of 89 on 5 tests. what will be the new mean if she scores a 95 on the next test?

(89+95)/6=X

Answer 1

Yep!

Answer 2

But I got 30.667 as my answer. So do I add that to the 89?

Answer 3

Oh, I see what's wrong.

You need to multiply 89 by 5 and then add 95.

[(89 * 5) + 95] / 6 = ?

Oh okay. Thank you
