Respuesta :

The cost per DVD goes down when the amount of DVD produced is bigger than 1000, this is because the cost of producing produnct in a bigger scale are always more profitable.

The bonus question ask us to find a function for the price of DVD at any value of x. The provided function

[tex]C(x)=\begin{cases}2500+1.5x\text{ if}x\le1000 \\ 2500+1.25x\text{ if}x>1000\end{cases}[/tex]

Already fulfill that purpose, then we can write

[tex]D(x)=\begin{cases}2500+1.5x\text{ if}x\le1000 \\ 2500+1.25x\text{ if}x>1000\end{cases}[/tex]
