The U of A Bookstore offers a program of reproducing class notes for participating professors. Professor Yataha teaches a freshmen-level class with an enrollment of between 200 and 250 students, uniformly distributed. A copy costs $10 to produce, and it sells for $25. The students purchase their books at the start of the semester. Any unsold copies of Professor Yataha’s notes are shredded for recycling. In the meantime, once the bookstore runs out of copies, no additional copies are printed. The bookstore wants to maximize its revenues. Using continuous approximation, how many copies should be printed?
