You and your classmates create 25 self-portraits to sell at the PTA auction to raise money for your school. In order to pay for the materials you bought to make the self-portraits, you need to sell each of the self- portraits for $1.00. When transporting the self-portraits to the auction, one of your parents accidentally drops three of the self-portraits in the street and they are run over by a school bus. What is the new minimum price you need to set for the remaining self-portraits in order to pay for the materials?
