Answer 6

solve the first equation for \(x\) in terms of \(p\) then make the replacement

Answer 7

\[p=-\frac{1}{8}x+900\]
\[p-900=-\frac{1}{8}x\]
\[-8(p-900)=x\] or if you perfer
\[x=-8p+900\]

Answer 8

now replace \(x\) in
\[C(x)=\frac{\sqrt{x}}{200}+700\] by \(-8p+7200\) to get
\[C(x)=\frac{\sqrt{-89+7200}}{200}+700\]

Answer 9

whoa nelly i made a typo above, should be
\[x=-8(p-900)\] or
\[x=-8p+7200\]

Answer 10

and final answer should be
\[C(x)=\frac{\sqrt{-8p+7200}}{200}+700\]
