- Create an application for Paula’s Portraits, a photography studio. The application allows users to compute the price of a photography session. Paula’s base price is $40 for an in-studio photo session with one person. The in-studio fee is $75 for a session with two or more subjects, and $95 for a session with a pet. A $90 fee is added to take photos on location instead of in the studio. Include a set of mutually exclusive check boxes to select the portrait subject and another set for the session location. Include labels as appropriate to explain the application’s functionality.
