To write a function f describing cost of sealable books.
The printing and binding cost for a college algebra book is $$\10$$.The editorial cost is $$\200,000$$. The first 2500 books are free.

Calculation:
Let the number of books be x .Since the printing and binding cost for a college algebra cost is $$\10$$ -The printing and binding cost for 10 algebra books is 10x The editorial cost is $$\200, 000$$. The first 2500 books are free.
Thus, the average cost of sealable books is
f(x) = total cost/number of sealable books
$$f(x)=\frac{10x+200,000}{x-2500}$$
Hence, the required function is $$f(x) = \frac{10x+200,000}{x-2500}$$.
