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