Okay thank you! The answer that was given was my teacher's answer and I was going crazy trying to figure out what I was doing wrong.

Oops sorry.. My question is how do you isolate h from P'(h)=-10+(6800/h^2) I know the correct answer is h=82.5 but I'm not sure how to get there. I know that the sqrt of 6800 is 82.5 but then what happens with the -10?

Homework Statement Find the maximum point of P(h)=-10h+4410-(6800/h) Homework Equations P(h)=-10h+4410-(6800/h) The Attempt at a Solution P(h)=-10h+4410-(6800/h) P'(h)=-10+(6800/h^2) P'(0)=-10h^2+6800 10h^2=6800 Divide both sides by 10: h^2=680 and sqrt both sides: h=26.1
