Question

suppose you create a graph of the cost function, c=20n + 500 of a new bookstore, and you also graph the revenue function, r=25n, where n is the number of books sold. On your graph, would the point n=150 in the loss section, the profit section, or the break-even section.

Answer 1

Answer:

Loss section

Step-by-step explanation:

Given

$c = 20n + 500$ -- cost

$r = 25n$ -- revenue

Required

Determine where n = 150 is

To do this, we substitute 150 for n in the given functions

$c = 20n + 500$

$c = 20 * 150 + 500$

$c = 3500$

$r = 25n$

$r = 25 * 150$

$r = 3750$

The above shows that the revenue is greater than cost for n = 150.

This implies that, n = 15o is the loss section.

Answer 2

Answer: profit section :)
