Question 58895: When Humans breathe, carbon dioxide is emitted. In a study published by in ASHRAE Trans, the emission rates of carbon dioxide by college students were measured during the lectures and exams. The average individual rate RL (in grams per hour) during a lecture class satisified the inequality:
[RL-26.75]<2.17
During an exam, the rate satisfied
[Re-38.75]<2.17
a. find the range of values for Re and RL.
b. The class had 35 students. Define TL and Te to represent the total amounts of carbond dioxide in grams emitted during a one hour lecture and a mone hour exam. Write inequalities involving absolute value which represent the ranges for Tl and Te.

You can put this solution on YOUR website! [RL-26.75]<2.17
During an exam, the rate satisfied
[Re-38.75]<2.17
a. find the range of values for Re and RL.
[RL-26.75]<2.17
-2.17
24.58
-----------
[Re-38.75]<2.17
-2.17+38.75
36.58
------------
b. The class had 35 students. Define TL and Te to represent the total amounts of carbond dioxide in grams emitted during a one hour lecture and a one hour exam. Write inequalities involving absolute value which represent the ranges for Tl and Te.
24.58
Multiply thru by 35 to get:
860.3
--------
36.58
Multiply thru by 35 to get:
1280.3
