Answer:
With 50 books sold, the point is in the loss section.
For [tex]n=50[/tex], revenues are 1250 and costs are 1500, which creates a deficit of -250.
Step-by-step explanation:
So, we know that the cost function and revenue function are:
Cost function: [tex]C=20n+500[/tex]
Revenue function: [tex]r=25n[/tex]
Now, for [tex]n=50[/tex], the cost and revenue would be:
[tex]C=20(50)+500=1000+500=1500[/tex]
[tex]r=25(50)=1250[/tex]
So, with 50 books sold, there is a deficit of -$250. Therefore, the point is in the loss section.
