$12.60 \text{ per disc}$

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} $.
