Ms. Picasso, sponsor for her school's art club, sells calendars featuring
student artwork to raise money for art supplies. A local print shop sponsors
the calendar sale and donates the printing and supplies. From past
experience, Ms. Picasso knows that she can sell 150 calendars for $3.00 each.
She considers raising the price to try to increase the profit that the club can
earn from the sale. However, she realizes that by raising the price, the club
will sell fewer than 150 calendars.
