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 to figure out how many cars are needed . Kiran doesn't think it matters in this case . Do you agree with Kiran ? Explain 12 + 3n >= 28 your reasoning .

Need an answer please!! :(
