Byfield: Triton students John O'Neil, left, and Carlina Arango, both 17, talk to Topsfield police Sgt. Richard LaBel and Newburyport police office Nora Duggan at the Credit for Life Fair at the school. Students play the roles of 25-year old adults and are “assigned” professions and annual salaries. Then working within a budget based on their monthly “income,” the students visit 14 booths over a 3 hour period to make “purchase” decisions utilizing cash, credit or savings.
