You offer a math tutoring service for children at the elementary and middle schools in your neighborhood. You normally charge $15 per hour. You recently received a message from the mother of a fifth grader inquiring about your services and pricing. She got your name from the mother of another student you tutor. You recognize her name as being from a family that owns a very large business in your town. You would like to charge her more than $15 per hour because you know the family is wealthy.
What would you do? Is it fair for you to raise your price just because you know the family has more money? What problems do you think you might experience if you charge customers different prices? Under what circumstances would you be justified in charging customers different prices?
