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 = 100 be in the loss
section, the profit section, or the break-even section?
O
A. You can't tell.
B. Break-even section
C. Loss section
D. Profit section

Break-even section. -

Step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
