(Modeling) Carbon Dioxide Emissions When humans breathe, carbon dioxide is emitted. In one study, the emission rates of carbon dioxide by college students were measured during both lectures and exams. The average individual rate RL (in grams per hour) during a lecture class satisfied the inequality

whereas during an exam the rate RE satisfied the inequality

The class had 225 students. If TL and TE represent the total amounts of carbon dioxide in grams emitted during a one-hour lecture and exam, respectively, write inequalities that model the ranges for TL and TE.
