Question:

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

|RL - 26.75| ≤ 1.42,

whereas during an exam the rate RE satisfied the inequality

|RE - 38.75|≤ 2.17.

Find the range of values for RL and RE.
