Ansa, Joe, and Trevor all work at a summer park. One of them is a day camp director, one a lifeguard, and one a swim team coach. Because of their jobs, they wear different colored shirts to work.

Ansa, Joe, and Trevor had a meeting. Joe said that his swim team would have practice tomorrow. Joe told the person wearing the blue shirt that he was working late tomorrow. Trevor told the lifeguard that the other guards should also wear red shirts when they work. Then, the person wearing the green shirt left the meeting.

What is each person's job, and what color shirt is each person wearing?
