28 students travel on a field trip. they bring a van that can seat 12 students. elena and kiran’s teacher asks other adults to drive cars that seat 3 children each to transport the rest of the students. elena wonders if she should use the inequality 12+3n> 28 or 12+3n ≤28 to figure out how many cars are needed. kiran doesn’t think it matters in this case. do you agree with kiran? explain your reasoning.
