. The mayor of the small beach town of Mermaid Cove, CA, talks about her town: "In total, there are 850 people over the age of 16 living in Mermaid Cove. We are honored to have 65 soldiers, who are stationed at the local military base. 300 of our residents work full time at the several locations of the local tavern chain "The Fixed Cod", while 50 people work part-time at the Shell gas stations and convenience stores in town. I know all the 95 full-time homemakers in person. There are 60 elderly people who have retired. We are proud of our community college with its 150 full-time students (all over the age of 16). Unfortunately, 10 of our residents got arrested last year and will be in the town prison for the next few years. The rest of the people do not have jobs, but they would like to have one. However, 20 of them did not actively look for a job in the previous four weeks." Show all your work when answering the following questions: a.
