Multiple Choice

Professor Kremepuff's new, user-friendly textbook has just been published. This book will be used in classes for two years, after which it will be replaced by a new edition. The publisher charges a price of p₁ in the first year and p₂ in the second year. After the first year, bookstores buy back used copies for and resell them to students in the second year for p₂.

The number of students taking the course in the first year who are willing to pay $w to keep the book for reference rather than sell it at the end of the year is 50,000 - 2,500w. The number of persons who are taking the course in the second year and are willing to pay at least $p for a copy of the book is 30,000 - 500p. If the publisher sets a price of p₁ in the first year and p₂ <= p₁ in the second year, then the total number of copies of the book that the publisher sells over the two years will be
