Ok. I have one more question. The mean height of 5 students is 59.4. If one of the students leaves, the mean height becomes 61. What is the height of the absent student? I have this so far but still having problems solving it: 5(59.4)=4(61)+1(X);X=? Thank you so much.

You are doing it correctly.
5(59.4) = 4(61) + x
multiply it out...
297 = 244 + x
subtract 244 from each side
53 = x
