An on-demand printing company has monthly overhead costs of $1,900 in rent, $450 in electricity, $80 for phone service, and $230

kotegsom [21]

Answer:

$40

It means that when an infinite number of pages are printed in a month then the fixed cost will be negligible.

Step-by-step explanation:

Given that:

Monthly overhead costs in rent = $1900

Costs in electricity = $450

Costs for phone service = $80

Costs for advertising and marketing = $230

Printing cost per thousand pages = $40

If number of pages printed are $x$ thousand then cost of printing for $x$ thousand pages = $40 $x$

Average cost to print $x$ thousand pages can be given as:

(Total fixed cost + Total cost of printing $x$ thousand pages) divided by $x$

$\dfrac{2660+40x}{x}$

Now, it is given that an infinite number of pages are printed in a month, and we have to find the value that average cost would approach to.

$\lim_{x \to \infty} (\dfrac{2660+40x}{x})$

Let us solve the above limits.

$\Rightarrow \lim_{x \to \infty} (\dfrac{2660}x+\dfrac{40x}{x})\\\Rightarrow \lim_{x \to \infty} (\dfrac{2660}x)+40\\\Rightarrow 40+\lim_{x \to \infty} (\dfrac{2660}x)$

When

$x\rightarrow \infty\Rightarrow \frac{2660}{x} \rightarrow 0$

Putting the value in the limits, we get:

Average cost per thousand pages month would approach to $\rightarrow \$40$

It means that when an infinite number of pages are printed in a month then the fixed cost will be negligible.
