(Simplify your answer.)

Answer 1

$4855

Explanation:

The formula for mean is to add all the terms up and then divide by the number of terms, so in this case you would have:

`(3867+x)/(2)` = 4361

To solve start by multiplying both sides by 2

3867 +x = 8722 - then subtract 3867 from each side

x = 4855

Answer 2

$4855

Explanation:

4,361-3867=494 (add this to the mean to get your answer, the rest is just how you prove it)

4855+3867= 8,722

8,722/2 =4,361
