Answer
$12.60 \text{ per disc}$
Work Step by Step
Substituting $x=1000$ in the equation $C(x)=\dfrac{2.6x+10,000}{x}$, then,
\begin{array}{l}
C(1000)=\dfrac{2.6(1000)+10,000}{1000}
\\\\
C(1000)=\dfrac{2600+10,000}{1000}
\\\\
C(1000)=\dfrac{12,600}{1000}
\\\\
C(1000)=12.60
.\end{array}
Hence, the cost is $
12.60 \text{ per disc}
$.
