Step by step explanation:
Assuming x as the number of books, the function of production cost is:
[tex]C(x)=45240+9.25x[/tex]
And the selling price function would be:
[tex]S(x)=25.5x[/tex]
For rhe production cost to be equal to the money from sales we have:
[tex]\begin{gathered} 25.5x=45240+9.25x \\ 25.5x-9.25x=45240 \\ 16.25x=45240 \\ x=\frac{45240}{16.25} \\ x=2784 \end{gathered}[/tex]
Answer:
The publisher must produce 2784 books
